External plug help!

Behind the front wheel well on each side, I have this plug hanging down.



I haven't been able to put a volt/ohm meter to it yet to find out what gives it power..

Anyone know what it is for?

It may be for running board lights or something. I'm not sure.

That's odd. I have a completely different line going to the front brakes for ABS.

That's cool. I'm still scratching my head on this. I put a volt\ohm meter to it, nothing so far. Tried lights, interior, blah blah blah.. The only other thing I could possibly try is tone. maybe get lucky at the fuse box.

Oh

those are front wheel speed sensor connectors. Not all trucks have 4 wheel abs but they still put the connectors there. Your truck has rear abs only. That is normal, dont mess with them.

^^ What he said, I din't have 4w ABS on my 99 and has those plugs behind the fender liner. On my 03 they are plugged into the front wheel sensors.
