wire tap help

[usedep3]

Hi guys.

I'm looking for a few suggestions. I need to tap/splice into a circuit/wire that is energized after the car is started. I'm essentially looking for a wire I can splice into that will be on ONLY when the key is in the 'II' position.

Any suggestions?

TIA

You want to find the ignition harness they will be thick wires like 12 gauge. The wire that comes on only with the key is the black/yellow. It should be for for up to a 30a amp draw.
