    Well dude you probably wont need ANY relays -- your head units rem on lead should be able to flip on up to 5 or 6 amps... i run 5 off mine with no trouble...

    But, if you want to be "safe" , you can get ONE SPST (single post single throw) 30 Amp auto relay from radio shack for liek 5 bucks.

    Connect pin 85 to your head units rem on... 86 to ground... 87 to 12V power source ... and pin 30 to the 3 amp /2 processor tun on leads.

    If you cant find an SPST and get stuck with an SPDT... hook it the same except make sure you wire your five leads to pin 30 and NOT pin 87A..

    happy wiring :)
