ok so my ecu harness is converted to obd1 already, i have a b18c1 in my 90 hb all obd1, n stock manifold, wut would be the most proper engine harness to use?

the simplest thing i think would be a DA gsr harness?

help please

 

So your engine harness to the shock tower is OBD1 or you just used a adapter harness for OBD0-1?

 

if i understand right it sounds like you have a stock harness and converted it at the ecu plugs to obd1. If so then this is what you want. no need for any other harness, the one you have is the one you need.

 

use the harness for the dx....dont understand why ppl hack up a harness trying to make the whole damn thing obd1. pointless lol
