these 3

and this one


Need help with figuring out why these wires are disconnected/what they are for

 

You can get the factory wiring diagrams here: Foxed.ca

It has diagrams of the wiring and images of where to connectors are located on the body. There a two/three relays that attached to that frame rail I see missing.

 

I see both a 4 pin and 3 pin connector(s). Might help to know how many wires actually go to each one and what color code the wires are. Also assume this is a 79 manual.

 

83 manual gsl. our theory is that the ac has been pulled off and been tampered with. I’m from uk and this is a uk car.

Page 16-G Connector G05 "No 1 Air-Con Relay" 4 pin

How To Find: Look through the PDF wiring diagram link. Look at the wiring layout images near the area of the car these are in. You're looking for a line with a letter designation and a number. This represents the connector name. Do not look at the X-??? items in black. Those are the wire bundle designations or sub harness numbers. In the two I posted above you'll see connector B06 and G05. The page right before the car layout shows the connector configuration and wire colors. When looking at a connector for wire orientation, look at the back of the connector and NOT the front. I left the last one for you to find.
