I am needing some help with wiring or ideas, I swapped mustang 5.0 with Ron Francis harness in 92 ranger and I want to use factory gauges. First is temp gauge, I don't know which wire in engine bay that was hooked to gauge sending unit? I am assuming it entered in the cab on driver side. Wanting to also use factory tach, not sure how or which wire to use for that. The ron Francis harness has a green wire that would go to tach but not sure if will work with factory tach.
