Hey guys. I'm getting stumped on some of the wiring to the frame on my 98 f150. looking to see if anyone has a schematic or anything of the sort to tell me which wire goes where. any help would be greatly appreciated

 

You can check for a wiring diagram here.

I need a little more than wiring to the frame lol.

The red and yellow look like O2 heater wires. So were did that connector come from, over by the bulk head plugs, behind the 175 amp MEGA's?

Also, takeing a picture of the back of the connector would be helpful, - even if they're wrong.

 

Is that a trailer, tail lights, blinkers , plate light harness. ?

 

Well, I think that's what it is, I have it right here...helps to specify what the wires are for or what your working on.

Good Luck.

 

Here's the diagram from my 98 Wiring/Vacuum service manual. Hope it is of some help to you.

 

Based on the gauges and colors it looks like it could be tail lamp/trailer related but the OP at least needs to narrow down the scope before anyone can really help.
