hooking up gauges

anyone have a diy on hooking up gauges? sensors i can understand, have nfi where to hook up the power to though
i can probably tap into my head unit harness for power but i have no idea where to go to tap into the acc power

acc power can also be taken from the headdeck, most aftermarket units have a red acc wire, i would just double check this with a multimeter

yeah deck's got it, not hooked up though
so every time i hit acc, head unit turns on
when i start the car the head unit restarts again

all u need is a test light/multimeter to find the right wire, once u find it hook it up to your gauges and headunit. it should only take a max of 10mins to find it on the cars stero wiring harness

I usually tap power from the ciggie lighter (which comes on only when acc is on)
Light comes from, say like the night light, in the EG civic, the ash tray has one in the front centre console.

Down load the wiring diagrams of the appropriate car from the internet and look it up -These diagrams are free

can also get it from the interior fuse box, would be better cause your not splicing from another circuit.

i get power for my gauges from the interior fuse box thats under the steering wheel.. its easy to find the power, just need a test light and ur set.

you can also get constant voltage at the interior fuse box, as said above just need a tester which is constant and which is accessory.
