Gauge Wiring?

[Kandikid]

Just got 3 New HDI gauges (water temp - oil temp - oil pres) and have a few questions as i suck at electronic stuff.

Each has to be wired in at 3 points; Battery (assuming just power)

Ignition

Earth

Can I group the wires before I wire them in (the 3 power ones together, 3 Ignition ones, 3 earths)? So i only have to make 3 connections not 9.

Then actually wiring them into the car, which are the best wires to splice into for the power and ignition?

And the earth is fine to just connect to the chassis?

thanks

Ignition wire? Is it orange? Orange is illumination.

You can wire them all into one place, but if you start blowing fuses then you know why.

Earth is earth. The whole car is your earth, if so facto you have many earths so 3 more wont hurt.

A good wire is behind the radio for power. Its red, you cant miss it.

Its got

Red - Battery

Yellow - Ignition

Green - Earth

So im best off wiring them into different places? (say radio, cigarette lighter, and climate control?)

Thanks

yes you can

many people just wire the constant power off the headunit, the ignition into the headunit's acc and ground into the headunit's brackets.

problem with that is, when you want to just listen to music, your gauges go on.

oh don't forget to run an inline 10amp fuse for the constant power (just for added safety).

In the past, I tapped the power from my turbo timer harness, so the gauges only turn on when the barrel is set to "ON"

Yeah, dont wire into a constant 12v or the battery might go flat. but....

Stereo or cigarette lighter is good.

Youll find the stereo has both constant and acc power, usually yellow and red.

If you dont have a multimeter to test for volts, use a 12v lightglobe.

If there is some memory thingy in your gauges it might need power constantly, like the stereo needs for the clock and channel memory.
