wiring diagram

[Greg Dirienzo]

Does anyone have a wiring diagram for a 2007 sport trac? I'm trying to hookup a backup camera and I don't know which wire is pos or neg. I got a yellow/black wire and a brown/blue wire coming off the backup light bulb. Help if anyone can. Thank you

Greg, If you have a vom, it will help you trace + and - wires. The old analog type will not read DC volts if you have the leads reversed. The digital type will read DC volts with the leads reversed. The difference is. If the + lead is on a DC volt neg.

Greg, a bit "off topic" but if you do find out, would you PLEASE post an answer? I will be doing this later this month, would love to know as well.
