How can I get 7 remote leads?

So my system has grown substantially, and here is my dilemma..

I want to keep my factory stereo, but I have at leat 7 components that need a remote lead. What is the best way of doing this...I'll list the components and some othe items that may be of use to solve this problem.

3 amps, 1 line driver, 1 cooling fan, 1 automatic fan control (stinger SFC), 1 digital temp gauge...ughhh and I think thats it :-)..

I will have a 4 post isolator ( if anyone knows what the fourth post is for that would be knowledgeable information.) its supposed to be a 2 battery iso..Anyway a second battery, and a capacitor. Also if it helps I have a stinger SR200 at my disposal.

Thankyou for the help.

You could Bypass the Relay and hook a switch up instead.

As long as the switch is rated at a higher amp rating than all of the components combined. You could even get one of those with a light in it.

or

Use the switch to turn on the Relay . Hook one side to the ignition or hot and the other to one side of the Relay coil.
