National speed depot wiring harness from Ebay

Good luck. If you are VERY good with automobile electrics in older cars, you can probably install this harness. If you are not, I'd return it and buy a specific to your car (non generic) one. M&H harnesses are not cheap, but they are exact replicas of the original. That means the wire colors will exactly match a good wiring diagram. And THAT means you now have good directions to go by. I am pretty good with auto electrics (nowhere near as good as guys like @67Dart273), but I still got M&H harnesses from Year One. I did not feel like fighting the challenge of a non-exact harness.
