SSG Paddle shift fit

[Ubatoid]

Some of you may know I fitted an SMG wheel to the X a couple of weeks back but had some trouble getting the paddles to work with the autobox. Well with a bit of reaserch it would seem in my haste I purchased a wheel with SSG shifters on it. In my defence the seller did state it was an SMG wheel. Anyway it would seem that the SSG shifters are not at all compatible with the Xs gearbox. What needs to happen is that the paddles apply 0 volts when pressed to either the up or down signal pins on the ECU, the SSG is a different beast alltogether applying a resistance to the ECU rather than a straight 0 volts. Well after I got my head around what was going on, I pulled the switches appart to probe out the pins and contacts.
This is the wheel I bought, you can see the paddles dont have the + and - on them ( should have picked up that clue )



These are the switches removed, I have stripped back the heat shrink to expose the wires to aid in the probing. There is a master switch that goes on the left and a slave swith that goes on the right. What we need is the green wire connecting to ground - 0 volts and the brown and or red switching to 0 volts when the switch is pulled or pushed.




This is the circuit board off one of the switches with the resistor arrowed that needed to be removed.



This is the other switch with the ( two ) resistors removed



This is the master

Here is the master switch after some fancy re-wiring



The yellow and white wires that go to into the master switch are now redundant. The plug was nipped off and the wires grafted onto the red and brown wires while a seperate ground wire was connected into the green wire.

I would like to report it is all functioning as it should - it almost is, I have up and down shift on one paddle but only up on the other paddle, I suspect I neeed to bridge a couple of connectors in the master switch. I will report back as and when.If anyone wants any further info feel free to give me a shout.

Very tempting but not on a diesel until I win the lottery and get a 40d!

Here's a link to what the guys over the pond have been up to - not as detailed as yours yet.

thats a great bit of work to reconfigure the wiring!

The theory is quite simple once o had manages do discount the redundant wires. I will try and draw up a diagram later.
