which wire harness?

My friend has a 92 civic cx. He recently dropped a 94 civic si, a d15, engine into the car. He has the matching ecu but, what he doesn't have is a wire harness. Which harness could he use?

first off, the 94 si came with a d16 sohc vtec motor, not a d15. so hes either mistaken or its not a si motor.

get a stock wiring harness for his car, dont try to get a harness for another car and change wires to match, always modify hte stock harness. so for him he should get a civic cx harness

He can use any 92-95 civic harness with no problem (any one other than the Si or Ex he'd just have to add the vtec wiring to it). But isn't the engine a d16z6? That should have been what came in the Si stock
