Where does the pink wire go?
I'm working on my '72 F100 and have most of the wiring done. I have the wiring diagram, but can not make heads and tails of this. There is a Pink (fusible) wire with one red w/ blue stripe and a red with yellow stripe coming from the ignition switch. I can figure out were to connect it.
Also, if you could suggest the best place to get switch on power for my electric fans I would really appreciate it.
Oh, I almost forgot; where in the hell to the horns bolt to? The bracket has a hole and a tab, which if logic applies, should correspond to a round hole and a square "indexing" hole.
It wouldn't be the first time that my logic does not match Ford's engineers logic.

The diagram I have shows the red/blue wire going to the starter relay. The only Red/yellow wire I can find goes from the headlight switch to the dimmer switch.
The horn on my 69 mounts at the voltage regulator on the passenger side of the radiator.
If you have a thermostat for your fans I would run current from a source that is on all the time. Make sure you use an inline fuse.

The power to the fans comes from the battery but you need a switch on source going to the relays so the fans only get power when the truck is running. I already have the red/blue wire going to the relay, but what about the pink one?

The only "pink" wire that I can think of is the resistor wire for the ignition circuit. It runs from the ignition switch to a three terminal connector under the dash. The pink wire itself probably isn't connected directly to the ignition switch, but instead plugs into a wire coming from the ignition switch. There may also be a blue wire connected to the same terminal of the switch.
Your engine wiring harness for your ignition coil, oil pressure sender and temp sender plugs into that underdash three terminal connector.
If you have two horns, they should mount to the rad support, one horn on each side of the rad.
Hope this helps.
P.S. I just noticed that your truck is a '72, so it may be wired a bit different from my '69.
