Please help me learn what these are?

1986 K5 Blazer Silverado. Originally had 305, now has 350.

1st pic. comes out from the drivers side went under the carpet and connects behind the panel that conceals the seat belt mount.

2nd pic. dead center of the engine bay. i have not seen its female connector

3rd pic. originally under the headliner, the one on the far left in the picture appears to be a radio antenna and is a larger gauge wire than the other two. The other two are identical in gauge. All three are connected to some sort of mount on top of the cab. The mounts are all three identical.

4th pic. hose and connector that are taped together coming out of the firewall just beneath the junction box

5th pic. Small gauge black wire that was cut but had an identical piece less than an inch away that was grounded to the body under the drivers seat. I have replaced the connector on it and secured it out of the way. I do not know what it grounds.

Thank you for any assistance you may give. I do not know very much about wiring and electronics for automotives, other than common things such as how to test for hot vs ground and how to use a mulitmeter.

Re: Please help me learn what these are?

I think your pics are out of order

dead center engine bay is for the AC compressor
Hose and connector are for the cruise control (pretty sure)

Re: Please help me learn what these are?

The first two pictures are actually one image, when viewed as a list all the images lack the separation. In the first two was the male and female ends of the same wires, orange and white that im hearing are for dome lights.

Thank you for your reply. The motor was swapped and I dont think everything was hooked up correctly. My main concern is hooking up or rerunning thr essential wires for cranking andrunning. The wires you listed seem like they do not matter but if not hooked up will they cause any form of a problem?

The leads behind the seatbelt are for your dome light I'm pretty sure. This same circuit ties into the cargo light switch on pickups. And correct on the AC connector center of engine-it would have contained leads for the AC compressor as well as the file solenoid on the original Q-jet.

The last pic appears to be your seat belt reminder buzzer lead that grounds when you latch your seatbelt.

Not sure on the interior roof what's going on....nothing there as far as stock so no clue what the PO attempted to do there.

The roof ones look like a PO had a row of radio/scanner antennas.
