What the ISIS Multiplex System boils down to is basically a true-blue plug-and-play wiring harness. Wire each Powercell to its respective items, wire the Mastercell to each respective switch, connect power and the CAN cable, and you're off and running. No more untangling giant rolls of wiring or tracking down a short or other electrical malady throughout the length of the car under carpet and upholstery. With the short travel distances between the Powercell and its outputs and the Mastercell and its switches, the amount of wiring in a typical vehicle is decreased dramatically. This simplifies the job not only for the wiring guy but will also make you a little more popular at the upholstery shop since the trimmer will no longer have to hide that big clump of wiring running down the center of the floor. And cutting the time needed to install a complete harness means cutting down on labor costs, saving you a little bit of dough as well when it comes time to wire that new hot rod project.
 To communicate properly to...  To communicate properly to the Mastercell, the front and rear Powercells need to be specified by setting the address for each. The Powercells also act as individual fuse panels for each accessory, front and rear. The fuse holders and address boss is accessible by removing the clear cover. |  The switches that will actuate...

The MEGA Fuse is then connected to battery positive on the bus bar side using as short a wire as possible. |
 A CAN cable is used to connect...  A CAN cable is used to connect the two Powercell control units to the Mastercell input unit. This is the data cable that enables communication between the Mastercell and Powercell units. |  The first connector of the...  The first connector of the CAN cable plugs into the Mastercell. The second, center connector plugs into the closest Powercell control unit and a sealing plug fills the open input. The last connector plugs into the final, furthest Powercell (usually the Powercell mounted in the rear of the vehicle). The open input of this Powercell is filled using the terminal resistor plug identified by the "R" printed on it. This resistor balances the impedance of the CAN network to ensure high-reliability data transmission. |  An optional inLINK Radio Module...  An optional inLINK Radio Module let's you control any powered accessory from up to 100 ft. from the vehicle using a programmable, five-button key fob that allows up to 16 different functions such as keyless entry. |
