Dash wiring xe > mk2

[Pistol Pete]

I am struggling to wire my dash at the moment.

Loom is from an astra gte, car is a mk2.

Having looked at the guides, people talk about the green plug. I have this but only four wires not six, and no green one!

Astra mk2 loom the green will be at the x5 plug and you'll also need to run a temp (blue) from the stat housing, the only wires you need out of that plug are eml (brown/blue trace) and brown/yellow trace to ground out to give the fault codes

yar, the early xe is totally different. lee has wired em in before, and has a decent knowledge. ;)

ECU wiring kind of sorted that. Got a wire running from the stat aswell. But I have wired that from the round plug. Did the same for the rev counter. This is my only issue. Need a good signal for my vx220 dash.

[Sloth]

should be a green wire at the coil multiplug, use that. hang on i think i can find which term at the ecu to use.

[Sloth]

right, i can put a pic up later. heres what you need to do:

locate the ecu big plug

remove the 3 screws in it, 1 large 2 small, and remove the small trim

flip the plug over and prise the white pin part out of the black bit

you will now see the wires, locate the green one, and tap into it

job done. :)

[Pistol Pete]

That would work great. If there was a green wire to tap into.

[Sloth]

is there no green going into the ecu?

[Pistol Pete]

Nope.

[Sloth]

hmm i'll have a look at the wiring diag and give you the pin needed.

Pete what does the wire do that your looking for again mate ive got a pin diagram that may help you?

I could locate the pin number if that any use to you mate.

Im looking to get a good signal for my rev counter. At the mo its coming from the dizzy. I have a VX220 dash, so as this needs a good constant signal, one from a dizzy isnt good. I would like a signal from the ECU. Hopefully this will be good enough. It hunts at the mo. Very annoying.

[Damo]

Right pete my pin diagram says.

Pin 43 - signal lead tachometer.

Ithink this may be the one your looking for iirc.

[Pistol Pete]

Ok cheers. So is that counting left to right, top to bottom??!! Lol

[Damo]

I carnt be sure till i have a look at my spare ecu mate there should be pin numbers on the pin face mate.

[Sloth]

the pin numbers are on the white part of the ecu plug when you open it.

[Damo]

the pin numbers are on the white part of the ecu plug when you open it.

Cheers rob saves me checking lol.

[Pistol Pete]

Sweet. Will have a look later.

no prob, i will post the haynes astra 20xe wiring diag in the articles section thread on motronic tonight.
