After market wire harnesses

and you only need to spend about $500 more to rewire the car properly...lol

True, seems like no matter what, using any wiring harness you will be spending more on odds and ends etc no doubt.

I did my EFI Harness/Fuse Block etc from scratch and had to purchase all kids of stuff along the way. I was going to just build the cars other harness too but one of these kits will get me close enough to complete, Ill figure out the odds and ends as I go.
