I would suggest you send the OD Wiring Harness (or cut the OD Relay Connector off) and send to Robert McBride at 81 Ipanema, FT Piece FL 34951. Contact hime first at 772-466-3510 for pricing. He can make you a new OD Wiring Harness for your Henry J. All he needs is your old connector. The quality is GREAT! He also makes all the other Henry J Harnesses.
Best,
