There are alot of elctrical harnesses out there. I am working on a restomod 67 coupe with all of the upgrades like pwr windows, locks, fuel pump, halogen lights, electric cooling fans,etc. What is the best brand to use? ISIS has some newer technology but it is probably double the cost. What are your feelings about that system?

 

That does look like a cool system, but from my POV, that is more for the show car circuit than for us working folks.

Painless seems to be the most popular, but I can't comment on if it is the best or not. They are all so similar.

 

Ron Francis makes a great kit. It has circuits for almost anything you could think of.
