Hi there 

bit of a bizarre question

does anybody know what wire does what 

I assume the brown is for earth 

but then I'm left with blue/white yellow/blue and green/black 

any help would be great 

 

Um  why??.  What problem are you trying to fix? One wire and brown is going to be illumination and possibly the other 2 to make the contact to trigger the ecu mode. Are you trying to make it switch on with the engine every time?

I am just having a little play to see if I can get this to work for a bit of that's all baha 

OK but you will need a momentary type switch not on off . You need to use a multimeter on the switch wires to see which ones make contact when it's pressed and use those. But there will be a resister in there somewhere that tells the abs that the switch has been disconnected from the wiring too. Not as simple as it looks I'm afraid.

Ah okay okay 

I have a multimeter at the ready..

ah okay thanks for the information, may have to chose my next step wisely 

OK

pin 2 Brown wire = Ground

Pin 3 Black/Green wire = 12v Ignition supply from fuse 25 10amp

pin 4 Blue/Yellow wire goes to pin 27 on ABS unit

pin 6 Grey/Blue wire = Illumination supply

Ah that's great thank you, 

if you don't min d me asking where did you get that diagram from? 

Thanks again

Brilliant thank you!

Well I got it to work if anybody is interested haha

tidy did you have to use a resister in the end?

No I found that not wiring in the illumination wire worked a treat!

 

so the ignition supply went into live 

ground to ground 

hen the wire that goes to the abs port 27 for the light on the switch 

 

This is it now
