89 7.3 IDI Wiring issue
i have a rear brake/blinker not working. passenger side. have changed bulb(obviosly). no go. it hasn't worked for a while but just recently found out.
tested the socket to see if i was getting power to the bulb-NEGATIVE.
checked at the connector going back-NEGATIVE.
checked at the inside firewall-POSITIVE.
cleaned all of the connectors and re-greased them. still NEGATIVE.
could the socket be bad?
any help is great.
also i don't have a wiring diagram due to having no book.
ORANGE W/BLUE stripe if i'm not mistaken is the wire for the passenger side.
