Hello. I am trying to find a definitive answer. I have this wiring diagram, but I guess I am too stupid to figure it out. I am adding some gauge overlays and it says to wire it to the grey wire in the center that is the key on hot wire. this diagram is very difficult to understand at least for me. I have pulled the connector off the switch in order to wire it, and when I test it It still reads ground even with the switch on, and the wire is brown not grey. before I do anything to the wiring can anyone give me some insight into how to interpret this stupid diagram. thanks. I have several questions actually. my horn doesn't work, and my ac does not work. I know the compressor clutch is not engaging. basically I had been ignoring those problems. now I am in the middle of this and I can't seem to find a switched positive wire on this connector so I am trying to figure out if I have a blown fuse causing this or what. so first of all, is the brown wire in the middle of this connector supposed to be my switched positive. if I can be sure of that I can start figuring out where the problem lies. .. this is the instructions I received. and here is my wiring harness. thanks. I have actually done a lot of wiring over the years, but I am not sure I am interpreting that diagram properly and the pictures in the instructions do not match what I have. I have been planning on getting a repair manual but I have not done it yet. hopefully someone can help me here so I can button this up this weekend. thanks in advance.
