they say a picture is worth a thousand words... here it goes...

another thing to note is that the output from the switch to the relay pin 85 can be ANY gauge wire as it carries almost NO load... also this wire can be split to activate as many relays as you want...

alternatively you can connect pin 87 on the first relay to pin 86 any other relays (just make sure that those relays have pin 85 connected to ground)

additional notes: you CAN have Pin 86 pull from any wiring that is 12v +, if you want the lights(or whatever you are running for that matter) to only turn on when you have the ignition on all you do is attach PIN 86 to a wire that is only active when the ignition is on...
