Finished the Ranger enough for a test drive... a few issues.... nothing serious... so I got out my trailer light tester deal.... and plugged it in the four way flat harness and tried the lights.... and I got nothing.... so I took the tester to my Chevy.... and plugged it in and it worked fine so I know the tester is right but the four flat on my Ranger does not work... I did not have the time to work on this anymore so I started investigating on line and found out that MOST of these four flat wiring harnesses were factory installed.... is that correct?

So tomorrow I will check out to see if there is a fuse for this... and maybe get lucky with a blown fuse.... otherwise, I need to know what to check for next and suspect it will be to use a continuity tester on it and trace it back as far as I need to.... any other idea? Thanks....
