hey guys.
i have an 89 7.3, and i can't find a book for my wiring diagram. just a couple questions for those of y'all that are better at wiring than i am.

ISSUE: passenger rear brake light and blinker not working.
have changed bulb, checked for breaks in the wiring also. i am getting power to the inside of my wiring harness, but not to the connector that goes down the inside toward the back. BTW front blinker works fine and no issues with the flasher relay. i pulled apart the connectors and cleaned them and re-greased them. when i tested the socket in the back i wasn't getting any power to the blinker and brake side. is it possible the socket is bad? if so can i get another one?
on mine, if i'm not mistaken the brake/blinker on the passenger side is an ORANGE w/BLUE stripe? the other two are BROWN(running Light), and of course a BLACK.
i'm stumped and PO'ED!.
i'm not the best at electrical but i'm pretty sure i have tackled all issues.
also, checked where it came out of the steering column and it was good.
any help is very appreciated.

 

do ya have a test light man? its your best friend with wiring

 

i don't have a test light. mine blew up some time ago and i never got another one.

 

get one and pierce the wire that goes to the signal when they're on. if ya got power go further down the line. then pierce right before the connector. if ya got power there then test the socket.

 

see i tested the socket. no power. i tested at the fire wall where it connects to the back section to go down and no power. but i have power at the fire wall. i guess i will jsut have to take alot of time and effort to find it.
just really annoying

say what? i know this is a dumb question but i always have to ask. was the signal on when you tested it

 

just to make sure i'm looking at the correct wire. is the passenger side the orange with a blue stripe? no the brown? just checking.

 

oh man that's a tough one. let me check alldata real quick

Right hand rear turn stop lamp shows a wire color code of O/LB so orange light blue

 

cool thanks man

 

no problem. compare the operation to the left side to make sure your thought process is right. Left hand turn stop lamp is LG/O so light green and orange i'd say. Good luck
