I'm thinkin bout buyin a obd1 gsr and since my car is an obd2 99 civic dx h/b, what do i need ? I'm getting the whole motor w/ tranny, ecu and hopefully axles too. What about the wiring? I do have 99 si engine mounts, and engine harness already also. Need major help from some one who is an expert on this swap. One more thing, I want to switch to obd1 too.
