I got a 91 ef hatch with a b20v swap and had to pull the motor went to put it back in and the wiring harness is just falling apart. So I got a rywire harness for the engine bay all the plugs match up except one by the fuse box so im just wondering what its for and if I need it. Thanks.

 

That plug us essential for all your gauges, and providing power to your distributor. It also provides starter signal and an essential ground for the ecu. You sure you purchased to correct harness? I don't think rywire would have forgotten about that plug

 

I didn't get it straight from rywire i got it off a friend who got it with his crx, I thought it would match up but i guess not. So I guess ill just buy one straight form rywire. I Don't know too much about Honda's wiring, so I'm not sure exactly what harness setup I need. Anyone here know? or if there is a write up somewhere?

 

What exactly are you going for? Stock or tucked? I make harnesses all week long. Txt me if you like
