[QUOTE="sumone, post: 598937, member: 551481"] first check out that site he mentioned. but if you want a quick "rundown" which I'd advise against [IMG]//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif[/IMG].... ... pin 30 = big power source input pin 87 = big power source output pin 87a = untriggered big power source output pin 86 = trigger power source signal pin 85 = trigger power source return 30 & 87 are interchangeable, so are 85 & 86. basically, once the trigger power source signal has been "triggered", big power source input & big power source output are now connected to each other. otherwise big power source input & untriggered big power source output are connected to each other. if hooking up say 3 amps, - big power source input = say a 16ga wire from the battery...or a distro block from close by - big power source output = 3 wires to the remote terminal on the amps - trigger power source signal = head unit's remote turnon - trigger power source return = ground - untriggered big power source output = unused [/QUOTE]
