ok i just recently put a obd1 gsr harness on a obd1 b16 and i'm putting it into my 93 civic dx. Well on the passenger side of the car where the three engine harness plugs are there is a small plug with two wires that doesn't goto anything. I am confused because it's on the harness but doesn't plug up to the car. The 2 wires are a solid red wire, and a yellow w/black stripe. Thankyou in advance.
