Deciphering Dodgy Wiring

[jacksonneaves]

Hey I'm trying to clean up some dodgy wiring while everything is out of the car can anyone please tell me if this is factory or not? And if not what is it supposed to look like? Thanks

Picture One looks like aftermarket relays - for spotlights / driving lights?

What year is your car BTW?

 

Picture Two shows the wiring loom extension from dash loom to console area, looks about right. It feeds the radio, console switches and console lights.

But not the red and blue wires / blue tape, can't tell from the photo which connector(s) they are hooked into, they look like aftermarket stereo wires.

 

Best you grab a wiring diagram, for the car year and market sold in.

The connector with the green wire (shown circled below) is the 'loopback connector' which can be removed and used for a hazard light switch.

Sorry it's 1975 260z. There aren't any driving lights but I'll follow them tonight and see where they go I would rather not have them if they are not being used. Also thanks I'll have a read and maybe hook hazards up

The relays look to be for the original headlights. The cars with no relay resulted in dull yellow lights due to voltage drop issues. It's not uncommon to put relays in, The original headlight wiring have been used to switch the relays.

 

The original lights are earth switched i.e. they have +ve all the time and the earthed is switched on the low or high filament using the dipper switch.

 

The relays could still apply the same type of switching and just used to reduce load of the light dipper switch and remove voltage drop, or what could have been done (what I did on and older 240 I had) is to use the original -ve switching to switch the relays, with the relays switching power onto the lights.
