[nova20xe]

C20xe engine running no ecu

I have a grey wire with green trace
Brown wire with white trace and a black
White wire with black trace and a black

There are in the engine loom but have no idea where they go to. Any ideas

There's a couple of double plugs that can be ignored, around where the ECU plugs in. One's for diagnostics flashed via the EML for example.

All you need to get it running is the large multi plug.

You dont need that multi plug at all. Shocking bodge jamming that in.

Brown/white, is use to flash the codes out. Keep that out and handy as you just need to touch it to a ground to work.

Well I've no multiplug anyway. Car running carbs so wiring is pretty basic. I got the white with black trace and the black as being the reverse lights wiring but no joy on the other 3. What colour is the horn usually wired in?
