Material list:
Automotive SPDT relay switch (Radio Shack) http://www.stevemeadedesigns.com/board/ind...showtopic=22495
12 AWG wire (You will be rewiring almost everything and upgrade from the 16 AWG)
Butt connectors (For the bottom of your relay switch you will need 4 of them)
Step 1.
Get a accessory line from your head unit. run it to your relay switch #86
Step 2.
Ground your relay. #85 to the ground or chassis of your car.
Step 3.
Run a constant 12 Volts to the relay #87. (Straight from your battery)
Step 4.
From the relay #30 run a wire from this to your voltage controller. (Don't plug in anything yet, just make sure it is long enough)
Step 5.
On your voltage controller there should be a yellow 16 Gauge wire. (If not yellow then the wire to your left, where the dial is) Remove that wire. Now with the new wire you ran to your Voltage controller #30 run that where the yellow wire is (Or the color of the wire that was in the left side)
Step 6.
Leave the middle wire alone. It should be black.
Step 7.
Where the plug is at your alternator there should be a yellow wire with a white stripe, cut that leave about 4 inches from the alt plug.
Step 8.
Run a new wire from your voltage controller to the cut yellow wire at the plug. Solder it or crimp it. Now on the right of the voltage controller there should be a blue wire, disconnect it. and screw down the wire you just ran to the plug to the voltage controller.
When you turn your car on and your head unit turns on, you should hear a click and then the alt will turn on.
Please tell me how you made out, or if you need any help let me know.
