I am in the final stages of getting my dashboard assembly ready for installation.

Gauges installed, switches installed, fascia installed, heater controls installed, new glove box.

I just have a few wiring questions however, since I found some discrepancies between my dash wiring harness and the diagram I am using from the B120 Chassis and Body Service Manual.









Can anyone confirm that the room lamp harness is a RL (red/blue) wire and not just blue as the wiring diagram shows [no. 7]?






I cannot find the G wire that goes to the "flasher unit" [no. 14]. I have a red wire that connects to a green wire. Is that the wire to the "flasher unit"?






This connector with YR wires and a bulb is not in the wiring diagram. What does this go to?




Am I missing the R and G wires to the hazard switch? [no. 18]




My combination meter [no. 20] does not match the diagram. My wires seem to go the other direction to the diagram. And there is an additional YR wire.






Did I install the correct wires to the Speed Switch Amplifier (SSA) [no. 22]? Red wire from top of gauges to black wire on the SSA?




Also the G wire from SSA to GY wire on harness?




Also where the hell are my wires to the tachometer? The two BW wires connect to what?




Which LW wire goes to the "heater control switch" the short one or long one [no. 23 & 26] ? Also why is there two wires to the "heater control switch" (the LW and B wires) when there is only one connection to the "heater control switch"? I connected the B to B and I hope this is right.






What in the hell is the "cooler" [no. 25]? and where the hell does the BW wire to the "cooler" connect to.




I have this extra connector piece near the BW wire to the "cooler" that I have no idea what it goes to. It is not in the wiring diagram.




Is the long LW wire to the radio [no. 26]?

The book looks like the 1978 export manual.
This one? And what year is your ute & wiring harness?

Correct. My ute is 1980 model

24013-G2170

The 'cooler' was an option extra, availiable only on the limited edition "Fonzarelli" model - US import only

HEYYYYYYY

I checked with Fonzarelli, just got a text back.

Quote:He says "cooler" means Aircon, but he's never seen it installed , mmm.

The diagram is for 1978 and your ute is 1980. Several changes may have taken place.

24013-G1270 is Instrument Panel harness for export models, exact year range unknown.

Quote:That is an older tachometer. The one for newer models doesn't have the current loop wires, but a single signal wire, like a typical aftermarket tachometer.

And besides, 1200 utes didn't have a factory tachometer option. Sedan/coupe will have a place to plug in that old tachometer.

See Tachometer Wiring for information on using older 1200 tacho in newer 1200 ute.

Alright much appreciated guys. That solves the mystery about the tachometer and the "cooler".

What about the rest though? Can you guys confirm if the LW short wire or the LW long wire goes to the heater? - that seems like a simple one that you guys might know. Does the black wire or the LW connect to the heater control switch and where does the other of the two wires go to?

Also is the Speed switch amplifier connected correctly? Should I even have it installed since I am not using the factory emissions components or factory carburetor?

Is the room lamp connection the LR wire I found in my harness?

Where is my wires for my hazard unit?

AAAAAAAAAAAAAAAAAAHHHHHHH I am going to explode.

I just don't want to turn the key on my ute for the first time and have it burst into flames and burn to the ground.

As long as you have the Fusible Link system intact it should not catch fire.
