   Combo and T/S wiring help 12/71

   I see on other posts, pics where there are big red and big wh/red wires for the headlights. Can anyone tell me where these wires go to. I see on the basic S30 wiring diagram that the blue with wh stripe goes to the wiper. Also the red goes to the washer and the gr/wh goes to the lights. Is that correct ? In the first pic there's a red, gr/wh, gr and 2 blacks. ( 1 black goes to the other side ). In the second pic theres a y/gr, y/bla, r/blu and bla. Any help with where these go ? Dave refurbished the combo switch. If you want a pic of the turn signal side, I can do that. Thank you very much.

   LED dash lights

   I'm going through the hand-gouging ordeal of replacing two instrument light bulbs, specifically the left-side turn-signal indicator, and the high-beam warning light. A friend has suggested that given the difficulty of access, perhaps I should renew them all (good idea), but with LED rather than incandescent. He feels that LED will last forever, but given that we've had one household LED die on us, I tend to doubt that. Anyone have any experience with LED bulbs in dashboard applications?

   my early 280z uses the ammeter which I prefer to a voltmeter, anyway the problem is its not center when no current is being drawn. I was wondering if anyone knows off hand if there is a centering adjustment mechanical I would presume.

   Hello everyone, i have a turn signal problem driving me mad. Only thing left is that it´s the EU spec taillights. Plugs are fitting but no turnsignal. Tested switch, relay, fuse, Harzad switch.... Only that the hazard switch is from another year (other plug in 77 than 75). So far I think its wired in correctly though. So, anybody did a Eu taillight conversion and can explain to me what to change how? thanks a million, Richard

    Wiring a Driving Lamp Relay 1 2

    Hello! I am installing some driving lamps, and I will use a relay. I can wire the relay directly to a switch, but common sense (state laws) tell you that driving lamps are only supposed to come on with the high beams. So I have a 12V feed from the ACC circuit on the fuse panel to the relay, and I wanted to wire the relay's ground to the high-beam (ground) wire so the driving lamps come on with the high beams, because the high beam switch goes to ground, right? Attached is a simple schematic. BTW- It's a 1978, so the High beam wire is a RW wire, according to the FSM I atached a simple diagram
