Ok so to make a long story short. I am trying to finish up the replacement of my heater core. I have the whole truck back together except for a few wires on the driver side. 2 connection ports with nothing to put into them (pictures included) they are the blue and the green ports. And 3 wires, one of which are connected to the steering column. I can’t seem to find where these go. Any help i can get with this would be great. If anybody has a picture of their wiring in this area behind the emergency break or the one at the steering column that would be great too.

My truck is a 2003 1500 4.7 V8 4X4, if that helps.

 

can someone look up by there gas pedals and see if both of those ports have something in them?

 

If I remember right the Blue one is for trailer brakes, so if you don't have those it will be open.

I don't have my truck at work so i cant tell you on the rest sorry.

 

The blue connector is the trailer brake connector. Does the other one have four or five wires, one of which is lime green with a black stripe? If so, it may have been unused. Mine was. I use the lime green/black wire for my switched hot.
