Wiring Harness
I now want to put in the prodigy controller and while looking at how they tied the old controller into the wiring, discovered or it looked like they tied into a wiring harness under the dash. They did not plug into the clip but spliced. Is this harness the one used to plug into for the rear plugs that the trailer hooks into. I know this is pretty screwey question since you can't see it but does the F250 have a wiring harness plug in hung on the bottom of the dash?
I believe it does but want to ask before ripping stuff apart.
Thanks so much for any info.
