I've been pouring over my chiltons manual for the '80-'96 F-150s and I cant for the life of me find a column harness diagram. HOWEVER, the connector on the column looks just like the one on my '77 column. Which means the pin-out SHOULD be the same. Hopefully...
According to the Painless instruction manual the pinout is as follows.
Wht/Red--Hazard flasher output
Red/Wht--Hazard flasher input
Ylw/Blk--Left tail light
Grn--Right tail light
Blu--Turn flasher
Grn/Wht--Front left turn signal
Wht/Blu--Front white turn signal
Blu/Ylw--Horn relay
Blu/Red--Gear indicator light...I think.
Hope this helps ya buddy.
