Hey.

I'm in the middle of a 20b build and am having a starter issue.

My starter relay is receiving 12v from the stock ECU when I turn the key to start position, but it's spose to be an earth signal!!

I have many sensors not connected but I'm pretty confident everything ip that IS connected is connected correctly.

I unplugged the ECU plug with the w/g feed to relay and earthed the relay as it shld be on the w/g pin and the starter turns.


Attached is the diagram. Can anyone offer a suggestion? Could it be a immobiliser problem? I've had the ECU out not running for about 12months. So I'm wondering does the ECU need to be re-coded?

I don't currently have a clock spring or steering wheel attached, and no condenser from ECU to earth. I shouldn't imagine these things would cause the ECU w/g to be 12v

Oh and my horn honks continuessly when I hook it up and turn on the key! I'm sure my car does not have the horn linked up to security system etc. my horn never honks when I press the lock button.
