Anybody used this now defunct CA company's 5.0 engine harnesses? They would convert 5.0 harness to the Turbo Coupe chassis. I made the mistake of not hooking up the check engine light and I think that made it impossible to pull codes when it misbehaves. There no power to the OBD port. Thanks
Those harnesses were something like $700 when the company was in business, no way I was going to pay that much...
A 5.0 harness should have power to the test port regardless if CEL is connected or not... I just connected the wires color for color and everything works on my swap, including the CEL...
