Made in USA

Thank you for purchasing the MC.1 Controller from Slam Specialties.  This page includes installation instruc-

tions as well as contact information for technical support.  If you have any questions about the operation of this 

unit, please call 888-352-5225.

The MC.1 is a two part control system for air suspension vehicles consisting of a handheld control unit and the 

accompanying receiver/driver module.  Microprocessors and solid state drivers offer fast reliable response while 

communicating with each other over a single wire, making the unit easy to install and flexible to move. 
There are two multi-conductor cables in the receiver box.  The 3-conductor is for power, ground and ignition; the 

9-conductor is for hooking up your valves. Please follow these instructions for wiring your MC.1.  

NOTE:

 the Aux 

wire is optional. The controller will funtion normally with or without the Aux wire connected.  AUX function is activated 

by a ground trigger.  When activated, the four fill valve outputs are energized until the ground trigger is released off 

of the Aux line.
