Re: Need Help Wiring Through Firewall
Go to walmart or autozone, and buy a test light. Maybe $5 or $10.
Take out the stock head unit. Turn your key to the on position.
Ground the test light and touch it to wires until the light on the testlight comes on.
Once the light is on, turn the key off.
If the light on the testlight stays on. Turn the key back on and move to another wire.
If the light goes OFF when the key is turn off....but then turns back on when you turn the key back on. That wire should work.
Then, while your at walmart or autozone, buy some T-taps. It will allow you to splice into that wire without cutting it.
