fenderwell wire harnesses?

[alberta 7.3]

I'm tearing apart my 2000 F350 to fix engine, and I noticed a wire harness on the backside (firewall side) of the inner fenderwell, down by the rocker panels. They are on both sides of truck and have a 2-pin connector. Any Ideas? They seem too far back to be front ABS sensor leads. I'll try to snap a pic tomorrow

I think those are for abs brakes.

those are the sensor connectors for four wheel abs brakes. The sensors havea long pigtail that connects there. Yours must be with no ABS or rear ABS.....
