Anybody ever rebuild a wiring harness for a TBI truck?

Picked up a '90 Suburban with a TBI 454/TH400 with the intent of using the engine and trans in my '77. I was planning on swapping the entire wiring harness over as well.

The factory harness from the firewall port under the brake booster and the portion for the TBI from the computer forward is pretty thrashed. I'm actually surprised this truck even ran. I haven't began testing for continuity, but that aside, most of the plastic connectors are broken or otherwise damaged.

Has anyone rebuilt a factory harness? Where did you source the connectors, etc? Is there anyone out there that makes a replacement harness for this truck?
