Looking for a COMPLETE harness for a 1954 M37.
Any leads would be awesome.
Thanks

If you want a civvy harness instead, mine is from Painless Performance-I installed it myself and it works flawlessly.

I checked painless... They didn't seem to have an M37 harness. What did you use?

I used their non-GM kit #10104, and the matching headlight switch. I took my time and installed it over 2 or 3 days.
