Wire amp for gauges???

[dil]

so i got the wire, the one he gave is 2.5mm, my existing one looks only about .5 ,maybe 1mm tops, he said it would work even though it is bigger.

Got it all wired up and NOTHING so i took the grounding wire off the sensors and grounded them separately and now gauges light up fine but there's no signal coming from the oil temp and oil pressure.

So I'm presuming the wire I was given is where my problem is?? But should I not be getting a signal anyway, even when it is a bigger wire???!!


Hey all!

I'm fitting my oil pressure, oil and water temp gauges. The wiring for the sensors for all gauges is too short so I need to extend the wires, (Green and Black[-]).

Just need to know what amp wire I need to add on to these wires, 5amp, 7amp etc???

cheers!
