Hey guys looking for some advice on installing Sunpro Supertach II on my 72' F250.
Im grounding the black to the engine, green wire to negative on coil, white wire to the headlight switch, and the red to the yellow wire behind the ignition switch. Do ya'll approve? Id rather not mess with anything on the ignition switch, is there another place youd guys reccomend id tie in the red wire?

Re: 1972 f250 Supertach
I would just hook the red wire to the fuse block to a switched 12V source. With the black to under dash for ground, but your way sounds ok.
May your sails stay full, and your knots not slip. Unless a slip knot.
