So I'm starting the process of restoring my dash harness, trying to identify some of the terminals that weren't connected to anything or don't match anything in the wiring diagram. I'm hoping there's some wiring gurus that can help. 

I've been using the 71 early diagram as I believe that's what my car is.

I hope this isn't too confusing....

Picture One:

Fog Lamp wiring - Red - taped off = correct. The engine bay harness has corresponding wires also taped off near the horn wiring R & L sides.

You are also correct about the 6-pin connector with the greens - hazard switch - which looks bypassed by the factory.

Picture Two:

Top connector (blues) is the stock power antenna (which operates differently than the more modern auto antennas)

Middle connector - The two whites are for the speaker. The blue I don't remember, but I think it may be power to the radio...

Picture Four:

Correct on the three greens to the horn relay.

Our left hand drive cars have the horn relay in the same place - it just happens to be drivers side with all the speedo, tach and steering column wiring. We DO NOT have any 4-pin connector on that side that looks like yours (edit: because the US cars didn't have a PASSING RELAY...) End of the dash harness on the left side is just door switch and horn relay. My guess is that it's for the passing relay and the non-US wiring diagram shows similar wire colors.

Picture Five:

Correct on both. Our turn signal flasher is left side near the steering column, Hazard flasher is right side near the body and engine harness connectors.

Picture Seven:

I think you need the 1971 FSM Supplement for that. Weird to me that the Body Electrical doesn't show wiring for the Blower Motor or Switch - which that small harness must be. The Heater and Ventilation System is described in the Supplement.

@cgsheen1 Thanks so much for your knowledge mate! Ill check out the FSM and see whether there's anything in there

In the first picture...what are the individual wires - red with blue stripe with female spade and solid black with male bullet...? What do they connect to...? Thanks...Ryals

Don't see them.. i do see a red one with a BLUE line on it and a black with male bullit..  i don't know where it's for but the black with male bullit is the negative side..🙂

My bad...BLUE is correct. Thanks, Dutch...!

 

A fault easely made.. and maybe you can find that cable in a service manual? (schematic diagram)

Red/Blue (RL) under the dash is generally for lighting (power to bulbs). Hard to tell from that picture but the location is near the center. My 260Z has a RL/B set in that area for the Map Light... However, the 240Z schematic shows a singular RL to the Map Light (must ground - sorry Earth - to the dash frame?). But, it's probably a light for something... It's too short for a center console indicator and the harness ties up tight to the top of the dash frame so stands to reason it's something near the 3 small gauges maybe.

Thanks...! I will get through this, but only with the help of others like you and Steve, etc. I'm wondering if the early 260 wiring diagram may be of better use to me...! All the best...Ryals in north Georgia.
