I'm going through my wiring harness with a fine tooth comb and I have a couple of questions.
In this picture: I. What are these four connectors for? I think they are for the center console. Is that right? II. Is this green wire for the parking brake switch? III. Are the brown wires for the door switches and the black for the internal light.  What is this for? I believe it mounts somewhere under one of the seats and is used to connect the harness wires to the door switches. Where does it mount? Which accessories are connected through it?  The plastic connector holder on my turn signal switch is very brittle. I don't suppose there are any aftermarket replacements?  Lastly, where can I purchase all new grommets for the wiring harness? Thanks. George |

QUOTE If both wires go to both switches, in parallel, won't both doors have to be open to break the circuit? When a door is open the switch closes completing the circuit to ground QUOTE Do the door switches ground through the chassis? From '74 on they ground thru the switch body QUOTE I'm not sure exactly how the circuit works, but I know there are 4 connections on each switch. Looks like your diagram only has two, so it may not be for a 73. Correct, thru the '73 model year the switch had 4 contacts and grounded thru a wire. QUOTE Does the parking brake switch ground through the chassis? Yes on all years @GeorgeKopf @iankarr |
