Some might be for options not installed on your particular rig (?) Why not take a picture and post it here, some of these guys will probably know it exactly.

Do you have a wiper motor/washer pump installed? The 2 in your hand look to be for the wiper motor and washer pump, they should be 1 unit with 2 plugs.

The plastic square box that has all the wiring going into it is the firewall fuse box harness, the washer pump/wiper motor should be directly above it, between the brake booster and inner fender. I don't have a pic on my phone.

thankyou apparently the truck doesn't have a windshield wiper motor , now on another note when i turn on my headlights the fuel guage move to below E, otherwise it shows the correct amount of fuel, do you have any idea what could be causing that?

Here is the wiper motor and plugs, there are 3. These should clear things up for you.

As for your headlight question, I'de say best check the grounds first.
