hatepotholez Posted January 16, 2017 Share #1 Posted January 16, 2017 (edited) I'm now moving onto the electrical system of my 72 Z. None of my lights work except for hazards on the left side. All my gauges work, my ammeter is always a little to the right, unsure if this is good? My voltage at the battery is 13.5 and goes up when I rev. My brake light on the cluster works when the e-brake is up. There's a few wires not connected, most of them I have figured out. I wanted to know how to keep the wires from dangling all over the place, most of my wiring is connected. Can someone upload some photos on both ends of the firewall(interior), by the steering column, center console on how the wires are tucked away? I know on the right side the wiring is held in place by a leather/vinyl wrap but everything is just a mess. Thanks!!

jfa.series1 Posted January 17, 2017 Share #2 Posted January 17, 2017 Perhaps these will help. If your harness is not torn apart, everything pretty well falls into place with the factory retainers. I'm not sure by what you mean by "both ends of the firewall". I've got a couple of additional pics if needed. As to lights not working, you want to be sure all the grounds connections are clean and tight, have a bit of dielectric grease. The combo switch, turn signal switch, and the fuse box connections are also major culprits. Be very methodical in working through it - don't scattershoot.

I should have stated the interior side of it, but this is very helpful also. Link to comment Share on other sites More sharing options...

hatepotholez Posted January 19, 2017 Author Share #6 Posted January 19, 2017 Anyone have a pic of the drivers side door light jamb switch connection, the brake light switch. And can someone tell me where this connector goes? It's green, black, black.Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
hatepotholez Posted January 19, 2017 Author Share #7 Posted January 19, 2017 Oh also the horn connections. Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
jfa.series1 Posted January 19, 2017 Share #8 Posted January 19, 2017 Your questions make me think you have not yet downloaded the FSM's for your car. Go to this link for the free PDF's and particularly get the '71 Supplemental manual - it has great details on all the dash wiring, including plug shape descriptions. http://www.xenonzcar.com/s30/fsm.html Link to comment Share on other sites More sharing options...

hatepotholez Posted January 21, 2017 Author Share #10 Posted January 21, 2017 I'll go over the FSM again. The black, black, green connector goes to a relay I believe. Can someone Identify it? Link to comment Share on other sites More sharing options...
