Its weird that yours was an Envoy and mine was a Merit and we had the same interior pattern.

Nice one :cool:

Mine was an Envoy and it had the wire, it's a bit strange. Envoy is something like 2 or 3 up from base model :lol:

Well today i cracked on with it, Pin number TWO on the plug nearest the bulkhead on the ecu IS the correct one, Into the 4/5th (cant remember) slot on the clocks and wala, Done and works.

Yeah, my 12v was the base model, no mods cons whatsoever.

It seems there isnt one unless its from a decent spec 12v model, Bloody vaux.

I never found the right wire neither :(

lol Basically i think ive cracked it by going directly to the ecu, since there isnt a wire anywhere it seems.

Will find out tomorrow.

I changed the clocks on my old one myself but the wire was there so it was ok.

Sorry but I'm too tired to understand the rest so I'll come back tomorrow :lol:

But dave, if you had done it yourself you would know its not that simple, there is no green wire coming from the ECU as it seems, Haynes shows X58/2, Since i could only find number two on the plug that goes into the car, its what im sticking with and il find out tomorrow.

Btw this is mostly due to me getting my hands dirty just now trying to figure it out.

There's a guide here for it - http://www.corsasport.co.uk/board/viewthread.php?tid=347302

The ECU is bolted to the back of the engine behind the inlet manifold, so not as easy a job as other models to fit the wire to :(

I know that... And any guide ive seen anywhere shows it for 1.2 8v's and up, which are all piss easy as the ecu is in the kick panel and theres a multi plug.

not every corsa b loom has the solid green wire for the revcounter, im sure theres a tutorial either on here or on allcorsa showing how to wire it in to the ecu

Unless you have actually know, dont bother replying.

No pin on the big black plug, cant see the wire anywhere, found one green from the wiper motor, other than that, cant find anything. Haynes says the wire should be coming of the ecu, but ofc its impossible to see with everything fitted.

obviously i cant just go off the coilpack.

Anybody got any light as to if the wire is there at all? if so where?
