Hi,

My Series 1 restoration project is going well and I have turned my attention to a couple of little jobs.

I want to wire up the water temperature gauge, my gauge is probably out of a Series 2 like several other parts on it.

When I got my truck it was a dismantle abandoned project and amongst many missing items was the entire wiring loom.

I know the gauge is fed from the voltage regulator, the back of the gauge has 2 space connectors so I presume the output from the voltage regulator goes on 1 and the feed from the temperature sensor is connected to the other.

I am worried that if I put the live feed on the wrong terminal that I might damaged the gauge so I am looking for confident replies as to which wires goes where.

I have attached a couple of photos of the gauge, front and rear.

Please note that the photo of the back of the gauge is upside down as I folded it down to take a photo in situ.

All of the wiring diagrams that I have looked at are no help.

I have the same doubts over the fuel gauge as well, which appears to be the same as in 2 connectors which are not labelled up and presumably 1 is a feed from the voltage regulator and 1 from the fuel tank sender.

Thanks, Karl.

On my series 3 and the wiring diagram light green goes from voltage regulator to top connections on the gauge.
The gauges on a series 2 especially fuel are different designs but if yours has a voltage regulator then should be the same as series 3.

definitely looks like a series 3 gauge, my s1 gauge doesn't have a temp bit, but looks like your panel has been modified so your electrics may not fit the s1 diagrams

Thanks Honolulujoe, can you confirm the wiring ?

not without taking the dash off, wouldn't be able to do that till after xmas now.

I have a photo but very cluttered light greens as said

Thanks but as I said, I have no wiring so telling me the colour doesn't help me

I just need to know which connector to connect the feed from the voltage reg and which to the sensor.

Thanks, Karl.
