I bought one from Caspers back in the late 90's when my stock harness was giving me fits. The installation was easy for me because I didn't have a heater box in the car, so my advice would be to pull out the plastic inner wheel well to do it properly where the harness comes through the firewall if you still have your heater box in the car. I just pulled it out last year and made a custom harness because I was starting to get electrical issues again. That had nothing to do with the Caspers harness, it was me pulling my motor in and out of the car over the last 17 years and tugging on the harness. That harness is a life saver if you are having problems. You will have no issues with it. A question that you could ask before purchasing it is, is the engine harness separate, or does it also come with the harness that goes into fuse box on the driver side. I pulled out my buddies harness the other day and his car has a completely stock harness in there. The fuse box harness is also connected to the engine harness. It gives power to the ignition module and I believe one of the components near the map sensor. Just take your time installing it, and make sure you anchor it properly so the harness is secure on the fire wall and outer fenders. You want to avoid movement near the connections so nothing is being moved around that eventually cause you grief.
