hello all, I am transplanting a LS1 into my 66 C10 and am at the stages of getting a wiring harness. Can y'all recommend the best ones out there?

Truck harness or LSx harness?

I've used American autowire for the truck side harness
For the LS I've used psi...
Both are top quality

A lot of information in the LS swap section that may help you with this.
