HELP NEEDED- Wiring
Coming to the forum again for help with a problem. Over the weekend I did the foglight mod to allow foglights to work on high or low beam- https://www.ford-trucks.com/lc/lc.ph...%2Ffogfix.html
Mod worked fine, but then I noticed that taillights and front marker lights are now working intermittently. Also, the foglights work sporadically now also. I DON'T believe it is anything to do with the mod. I found a great diagram of the wiring schematic on the Ford Fleet site, but it doesn't list what each wire is for- https://www.fleet.ford.com/truckbbas/non-html/2004/bb_pdf/190.pdf.
Does anyone have a wiring schematic for the PSD that has a breakdown of which wire controls what? Or does anyone know which wire controls the marker lights/taillights? If you look at the Ford fleet site, it is the horseshoe connector, labeled A. I'm assuming it is in that connector as that is the one I pulled to do the mod. As always, thanks for your help.

Let me revise the question- does anyone know if the number 13 wire that you cut to make the foglights work on high beam or low beam, also controls the tail lights and front marker lights? Thanks!

Pin 13 of connector 270a (that's the connector your disconnected) supplies 12v when the high beams are on. The other pins on that connector don't seem to have anything to do with tail or marker lights.
Since this problem happened at the same time as the modification, it is possible that another connector that ties into the central junctio box got partially disconnected. Connector 270b would be a good item to check first.
