Rebuilding Harness

Not sure if this is the place to post this or if there is a better thread?
Curious if anyone on here offers any harness rebuilding services? Or if anyone knows a good company that offers this?

Essentially, my engine side harness (injectors, o2 sensors, etc) is old, dried, melty, partially chewed, remote start spliced(I think?), and tired. IT STILL WORKED. Mostly. Ha!
So, I’ve currently it off the vehicle to send it somewhere?

Thanks.

I guy in my local club made a replacement himself using all new components. I will probably do the same if all of the connectors I need are still available.

Painless make a replacement harness that should make it a bit easier.
