Hey all
Can anyone who has done the z20let conversion pinpoint me in the right direction if possible.
This is the standard corsa wiring that comes out the bulkhead to the starter/alternator etc.
This leads up through to a multiplug at the brake fluid reservoir that has a blue/white wire and a red/black wire

My question is, do I need to make use of all these original wires as the engine I have already has the starter/alternator pre-wired up through the z20let wiring loom?
Any help appreciated as always
