Fixing Internal Wiring Harness

Hi I just recently purchased a 1970 Cougar XR7 and are working on restoring the internal wiring. As I was taking out the wiring harness, I noticed that the fusebox wiring contacts were so corroded that they are no longer usable by themselves. Most of the wiring harness looks to be in good condition though, but should I just get another wiring harness that has the contacts and fuse box i need or is there a way to repair the wires. If so please let me know and thanks.

There’s some guy called Midlife who refurbishes Mustang and Cougar wiring harnesses, including the fuse box. I think his website is


I’ll have to check them out. Thanks.:+1:
