another wiring loom question!

[phantome46]

I currently am having engine wiring loom issues and need some advice.

I have a ph2 williams loom - (2 purple wires only in the white plug) and a Ph1.5 loom (yellow wires in A1 and D6 but but Red in C7)

I want to install one in my valver with williams engine. My old valver engine had the ph1.5 loom on it and I had to modify this loom by creating an ignition switched white wire into the white plug to (B2) to power the fuel pump)

was this the only modification needed to make these looms compatible with the car or did i have some connections missing still?

I had read on the forum about an electric water pump for after the engine had been switched off?

HELP PLEASE!

Just plug the williams loom in and it should work, thats all i did on mine

what ph 1 car loom to ph 2 williams loom??

[Lunner]

Both cars have been ph2, but can't see the phase of the car makes any difference, the equipment level was the same on ph1 and ph2, using a Williams ECU, only thing is the imobiliser don't work with the willy ECU

[phantome46]

i'll try it but looking at the connections on the brown a yellow plugs then they dont match?

Dont think you can switch between phases of loom?

Same situation as you mate, think ph2 cars will run the willy loom fine but ph1 wont.

Shouldnt hurt to try. Let me know how it goes chap.

Yeah, phase 2 cars will take the Willy loom no probs.
Phase 1/1.5's is a different story!
