1989 Ford Bronco White wire with purple line

1989BroncoProject · Nov 18, 2019

I have a 1989 Bronco that I'm fixing up, and unfortunately the previous owners pretty much rigged a bunch of stuff on it. I'm currently working on the dome light, and found a bunch of cut wires. There is a white wire with a purple stripe that is constant hot, and I have no idea where it's supposed to go. Any help is greatly appreciated.

Yo 1989BroncoProject,

Welcome!

I went through this1989 EVTM, Emissions & Pre-Delivery Manuals, Partial via mrnewland1 in Google Drive @
https://drive.google.com/drive/mobile/folders/0Bz1eScc6s4raOHd0WlVnMUw4WjQ?usp=drive_web
Slow scrolling so download for the table of contents, etc.

And found one instance SO FAR of the w/purple wire in dome light circuit from Fuse #6 to cargo lamp in attached dome wiring diagram #7 of 20

Went though other circuits such as in attached speed sensor diagram. I searched for white/pink because some folks have confused pink (PK) for purple (P). BUT I SEE THAT YOU HAVE IT RIGHT!

I had to stop searching due poor internet speed.

Try searching. I'll try again when my provider gets their speed up to 1993 level.

Yo,

Fuse 6 serves at least:

Dome light, speed control, Borg Warner 1356 electric shift transfer case, cargo lamp, horn relay.

I figure cargo lamp is not working or has another power source since it w/p wire appears to me to be heading in that direction.
