Aftermarket harness.

So i didn't understand your original post, thought by "aftermarket" you meant non OEM.
But now I think you must have a race car, and want an aftermarket race car or street rod type harness.
Totally get it now. Yeah Evans makes a wonderful original style harness with correct plugs and connectors.
I'm sure you'll find something in your price range.
I have a 88 Dodge Dakota. Dropping in a 318 LA. Getting rid of the computer and the wiring is a mess. I am thinking now maybe EZ harness. Then order EZ ignition,wiper,head light switches etc.
