the prior owner of my M37 in Nebraska had it for 20+ years, and used it on his farm, and being a former M37 army mechanic took good care of it, and kept it under cover. He gave me many things with my truck, including a pamphlet by Jeff Smith, who provided comprehensive instructions and wiring diagrams, and lots of spare wire and assorted connectors for me to use. you need a circular crimper to do these correctly, which I bought on Ebay; the crimper works on both connectors. I used dialectic grease on the rubber Packard connectors to make them easier to pull apart when necessary. Let me try to post an illustration on how to use the small parts to make up your connections,
Stay safe.... HC
