I have an illustrated Ford parts book for those years. By the illustration It would suggest the harness goes at the bottom, or below the radiator cradle. It's a separate harness that joins at the LH side to go over to the RH side and then joins to a separate short harness to the headlight connections.
Ok so probably attaches to that bar going across the radiator brace. Now that I'm on the topic I was thinking about using a terminal block for the headlights. Would i just run the heavier gauge wire for each light to the strip, and from the strip to each light from the same post?
I mounted a terminal strip on the left inner fender panel. Terminals for the left signal, right signal, high beams, low beams, and park lights. The wires for the p***enger side run across in front of the radiator below the latch panel. I use 14 gauge for the park and signals and 12 gauge for the headlights.
