Wiring help

[68C101775]

Good afternoon all,

I’ve got a 68 I am in the process of LS/TKX swapping. With the swap I’ve got a terminator X to run the motor and Dakota digital RTX gauges with the Holley interface module.

I was planning to rewire the truck with an American auto wire or painless kit. My question is for those who have done similar, at that point is a full harness worth it? The Dakota digital has all its own stuff as well as the terminator engine harness. I didn’t want to spend the time and drop the money to just not use half the stuff off the new harness.

Thanks!
