Trying to use a scanner on my 1986 F150 4.9l automatic.
I got a single wire which goes to pin 48 of EEC module. That is the easy one.
I do not know the placement of the three wires that use the larger red connector. Wire 1 (tan/red) comes from pin 17 of EEC module, but which pin of red connector. Alt/ Pin S and a Black/wht which goes to pin 46 of EEC.
Does anybody have the pin out of that EEC-IV connector in their manual?
Thanks
