What are these for?

Nope. I had to buy the pigtail for mine from the dealer and wire it in. only did that because I have a tendency to rip those things off or break them somehow, just easier to replace that way.

ok. so splice or solder? same? different? how should I connect the wires?

 

[88GMCtruck]

splice is the action of connecting the two wires. There are 3 basic ways to splice wires. You can twist and tape (not a good idea), use crimp (butt) connectors (ok) or soldier and heatshrink (my preferred way)

What do I need to solder and heatshrink? Where do I get this stuff?

I got my 15w/30w soldering iron and solder from Radioshack, and get my flux and heatshrink from Ace.

ok thanks. is it fairly easy to do?

It definitely takes practice to make clean connections consistently. And technique is very important. You'll learn what works and what doesn't. There's lots of tutorials and how-to's on the internet, but one of the most important things to remember is to heat what your soldering, not the solder itself.

ok. thanks.

Check out how many wires there are in the loom. Either 95 or 96 GM started installing trailer wiring stubs that were sealed and taped, and tied up behind the bumper. There should be parking, LH, RH, parking lamps, ground, backup, 12+ constant, aux (with a taped pigtail by the underhood fuse box for trailer brakes) and a CHMSL lead.

The factory used those 4-wire T and most people do, and wire in a 7 way separate not knowing this set of wires exist. My 99 GMT400 had them, i wired the 7-way up there.

Yes I have seen that on countless truck's and most people never know it's there.

Exactly, the # 1 reason for soldering failures is caused by not heating what you are working on!! Don't ask me how I know!!!
