^Mani yes, harness no(Assuming Kevins is a kouki) you need an obd1 harness, the pinout between the two harnesses are different, so are the dash harnesses I believe.
I also have an s14 a/c compressor and bracket if your gonna run a/c
If you need it ill bring you that w/the door harness(I'll have to do this later on this week if thats cool w/you, i wont be able to do it the next few days, will be busy)
