The volt meter just has a black and red wire to the back and the water temp has the same. Are these for illumination then?

How do I hook them up?

 

black = earth red = live

wire em up to the lights feed as then it'll only light up wen you turn the lights on

 

Yeah Jim, I know that, but how do I get them to measure volts and temps??

 

oh...

well with just 2 wires... you cant (on the water atleast)

you'd need at least 3...

1 for ilumination live, 1 earth, 1 feed

unless ofcourse the bulb is seperate in your gauge n those wires are not ilumination ones...

i assume the voltmeter could use 2 wires n share the feed with the + illumination, but thats a wank way of doing it... n doubt even TIM are that rubbish...
