National speed depot wiring harness from Ebay
The last two “universal” harnesses I used were from Rebel,
Rebel Wire .:. Wire Kits for Real Rods
The wire leads were marked with that each wire was for along the lead, you could check to see if they are marked as that could help but it’s not for a novice.
Another thought is they are most likely a copy of another harness so maybe check painless wiring
Painless Wiring
and see if they have a diagram on their site that is the same harness as yours. Either way it’s a complete strip out of your old harness and install of the new one. I would check and see if it’s even comparable with you steering column harnesses as most are made to work with GM columns.
