TLS or TLR?

You're going to have to insert a resistor so the TL ECU thinks it can see the resistor in the TL ignition lock.

TLS >>

 

Sorry, it’s a TLR
Steve does the resister go on the orange/white wire?
What size resister do I need?
I’m a complete mess when it comes to anything electrical.
Your help is very much appreciated.:thumbup

 

....What size resister do I need?
.....:thumbup

It needs to be a 100 ohm resistor between the Orange/Yellow and Black/White wires.

 

six5 :thumbup
Could you give me a break down of what wires should be joined together?
You will have to excuse me as like I said I’m rubbish when it comes to electrics and completely out of my depth. I’m itching to get this bike fired up but don’t want to fry anything in the process.
are these what i need? http://cgi.ebay.co.uk/ws/eBayISAPI....l?ViewItem&item=290935604679&fromMakeTrack=true&ssPageName=VIP:watchlink:top:en :confused

 

Implanting a Ducati ignition switch into a TL...

OK Jay,

Just for reference, the wire colors coming out of the Ducati ignition switch appear to be as follows (on my screen).

From left to right -

Solid Light Blue
White w/Red tracer
Solid Red
Green w/Black tracer
Green w/Brown tracer
Solid Yellow

You can verify the connections shown in the diagram with an ohm meter. That way you know you are working with apples and apples.

Also, the Black wires in the Ducati schematic are the grounds. You'll notice that they go back the negative battery terminal. (This is with the exception of the black wires going to the fuse box - those are incoming power.)

Double check my work by consulting the TL wiring diagram on page 8-14 in the manual.


Now Duc versus TL...

The solid RED wire on the Duc switch is the incoming power from the battery. Not surprisingly, that will correspond to the solid Red wire in the TL ignition switch loom.

The Duc's Green/Blk wire corresponds to the solid Orange wire in the TL loom, because it is the one that feeds power to the loom once the key is turned ON.

The Green/Brown wire and solid Yellow wire are routed to a secondary switch for the lighting circuit. It allows them to turn on the parking lights without powering up other systems. So then.....

The Duc's Green/Brn wire corresponds to the solid Gray wire in the TL loom.

The Duc's solid Yellow wire corresponds to the solid Brown wire in the TL loom.

Apparently the Light Blue wire and White/Red wire are no used in this Ducati model. They can be left open in the TL also. No need to connect them to anything.

That should do it. Let us know how it goes.

 

Six5 :hail buy that man a beer
where do the orange/red and black/white wires that need the resister go to?
Are those resisters the right ones, are all 100ohm resisters the same?

Don’t suppose you could break the fuel pump wiring down for me as well?

Sorry for being a pain in the ass but I feel like a kid the day before Christmas, it’s been over a year since I started this and it feels like iv fell at the last hurdle.
All of your help is much appreciated :thumbup

 

Ok don’t laugh iv had a go at the fuel pump, not very successfully.
Black wire on Ducati loom to b/w wire on TL (earth)
Brown/white wire on Ducati loom to y/r wire on TL (injectors)
Blue/white wire on Ducati goes to fuel light
Ducati blue wire?
The remaining two wires on the TL loom look like they go into the dash somewhere?
Also how do I know which way around the wires need to be on the ignition coils, or does it not matter?

You basically had it figured out. :thumbup

Sorry, I meant to comment on the resistors, but forgot. The 100 ohm resistors in the ebay link will be fine. They are not all the same, but 1/4 Watt power rating will be plenty in this application.

Now, as for the fuel pump, below are the colors of the pump's four wires on my screen - top to bottom.

• You say Brown/White (looks like Black/White on my screen) (second color is tracer color - just to be clear)
• Solid Black
• Blue/White
• Solid Light Blue

The Duc's Brown/Wht wire is the incoming power to the pump; +12v through the fuel pump relay.
This corresponds to the Yellow/Red wire in the TL fuel pump loom.

The Duc's solid Black wire is the system ground.
This corresponds to the Black/Wht wire in the TL loom.

The Duc's Blue/Wht wire is fuel level sensor output. You'll see it goes to the fuel level indicator on the dash.
Since the TL uses a dual level fuel sensor, this wire may not directly correspond to either of the TL fuel level wires (Red/Black - higer level - light flashes; and Black/Light Green - lower level - light is on constant).

The TL fuel sensor uses thermistors that heat up and change value as the fuel level drops below the thermistor. I don't have the resistance values or voltage levels in front of me, but essentially (if I'm seeing things correctly), the fuel level drops, the thermistor heats up, the voltage drop across it increases, this lowers the voltage sensed by the instrument cluster; the fuel light begins to flash.

The Duc's fuel sensor is apparently a different sort. When triggered, it drives the Blue/White wire high to turn on the fuel level light. Since you are retaining the Ducati fuel pump/level sensor, but using a TL instrument cluster (correct?), a signal level converter of some sort will be needed to allow the Duc's fuel sensor to communicate to the TL's instrument cluster.

Member JoE. did a write up on the TL fuel level sensor in one of his GSXR instrument cluster conversion threads, but I can't remember if it is on the Zone or the Planet. :banghead He provides more detail - maybe enough to get you connected. Need to do some searching.....


The Duc's Solid Light Blue wire is the power line for the fuel level sensor. It provides power to many of the system gauges & relays.
This wire could be tied into a fused and switched +12v power source on the TL loom. It could be powered by the SIGNAL circuit (fuse #4); Orange/Green wire in the main TL loom.

Also how do I know which way around the wires need to be on the ignition coils, or does it not matter?

The larger terminal on the coils is the power feed. It normally connects to the Orange/Wht wire in the TL loom. However, as long as you are customizing this project, read up on the "Plus (+) Mod." It improves power to the coils.
The smaller terminals are the control lines. They go directly to the ECM. Be sure the wire colors are correct for front and rear cylinders.

 

Ok resisters are ordered.
I’ve had a long day and I’m sure the answer to this is in there somewhere but I can’t see where I should connect the orange/white and black/ white wires that come out of the TL loom for the ignition?
The Ducati fuel level sensor is broken, this is a common fault with these it can be fixed but they don’t last very long. I’m use to ridding with no fuel light (I just count the miles per tank full).
Does this mean that I could leave the Ducati blue/wht wire disconnected and the TL red/black and black/light green wires disconnected with no ill effects, other than having no fuel level light?:confused

 

.....I can’t see where I should connect the orange/white and black/ white wires that come out of the TL loom for the ignition?

Apparently, I'm missing something too. :confused

You are using a TL loom, ECM, and instrument cluster. Correct? What about switch gear? TL or Duc?

So then, based on my ignition switch outline earlier, the incoming SWITCHED power to the system is on the solid Orange wire in the TL loom. The current path then goes through the fuse box, side stand relay, kill switch, and it eventually emerges as the Orange/White wire for the ignition circuit.

So, I'm just not sure why you are tying into the Org/Wht wire. Can you elaborate?

As for the Black/Wht TL ground, you'll want to tie in at a location close to the battery with a large gage wire.

The Ducati fuel level sensor is broken, .....Does this mean that I could leave the Ducati blue/wht wire disconnected and the TL red/black and black/light green wires disconnected with no ill effects, other than having no fuel level light?:confused

Yes, leaving them disconnected won't be a problem. The fuel light should not come on. Post up if it does, and someone will get you sorted.

 

Now Duc versus TL...

The solid RED wire on the Duc switch is the incoming power from the battery. Not surprisingly, that will correspond to the solid Red wire in the TL ignition switch loom.

The Duc's Green/Blk wire corresponds to the solid Orange wire in the TL loom, because it is the one that feeds power to the loom once the key is turned ON.

The Green/Brown wire and solid Yellow wire are routed to a secondary switch for the lighting circuit. It allows them to turn on the parking lights without powering up other systems. So then.....

The Duc's Green/Brn wire corresponds to the solid Gray wire in the TL loom.

The Duc's solid Yellow wire corresponds to the solid Brown wire in the TL loom.

Apparently the Light Blue wire and White/Red wire are no used in this Ducati model. They can be left open in the TL also. No need to connect them to anything.

That should do it. Let us know how it goes. [/QUOTE]

So just to clarify I do this?

And then connect the orange/yellow and black/white together with a 100ohm resister?

It needs to be a 100 ohm resistor between the Orange/Yellow and Black/White wires.

Sorry if this is getting on your nerves it’s just not clicking with me

 

It needs to be a 100 ohm resistor between the Orange/Yellow and Black/White wires.

that should be orange/red wire as the orange/yellow is in the TL switch that i don't have.

That's right. The resistor is between the Orange/Red and Black/White wires. That way the ECM can read the value. If the ECM can't read the 100 ohms, it wont work - no ignition, no fuel, no nuthin'.

 

And the penny drops.:idea

Couldn’t get my head around the connecting an ECU wire to an earth wire for some reason.

Thanks for being patient with me.:thumbup

I’ll have a go to night and report back

 

six5 thanks very much for your help:hail, it works, I know have ignition and it turns over.:clap

But I have just tried to wire the fuel pump up and ran in to a small problem.

Ducati in there infonaut wisdom decided to change all the colours of the wires going to the fuel pump so none of them correspond to the wiring diagram.:banghead

I have a large red, large black, small black and a small white.

So I took a educated guess and connected the large red to the TL yellow/red (live)
Ducati large black to TL black/wht (earth)

Now the fuel pump primes when ignition is turned on, so far so good but how do I know what wire (small black or white) to connect to the TL orange/ green switch wire?

The engine cranks over? That's good news!

As for the fuel pump, I would leave the small Black and small White wires disconnected. Based on our previous discussions, those two wires likely have to do with the fuel level sender, which you are not using anyway. This guess is somewhat confirmed by the wiring diagram which also shows the fuel pump only has four wires - and you already found the two that make it spin.

 

Six5, thanks for all your help with this.:thumbup
I’m waiting for some fuel line fixing to turn up this weekend, then ill report back weather it run or not.
