Hose Information

Depending on other installed equipment, it might be necessary to

move the air/oil separation tank from its intended location. The

hoses used in VMAC compressor systems have a specific inner

liner that is compatible with our compressor oil. Use of hoses

other than those supplied or recommended by VMAC may cause

compressor damage and may void your warranty. Please contact

VMAC for replacement hoses and further information.

Part 1: Warranty and System ID

□ Complete the warranty form. The VMAC warranty form is located at

the back of this manual. This warranty form must be completed and

mailed or faxed to VMAC at the time of installation for any

subsequent warranty claim to be considered valid.

System Identification and Operating Instructions

The System Identification Number Plate must be attached to the vehicle

at the time of installation. This plate provides information that allows

VMAC to assist in customer inquiries and ordering of parts.

□ Mark and drill two 7/64-inch holes in the top of the cross member in

front of the OEM air filter box. Secure the plate with supplied self-

Part 2: Preparing for Installation

Preparation for installation is very important. Missing an item can cause

problems in the installation or even damage to components. Check off

each item as it is completed so that you do not miss any preparation

steps.

Ensure that you have filled out the VMAC Warranty

Registration. Install the System Identification Number

Plate and Operational Instruction Decal. (Please see Part 1

for details).

□ Locate the blunt-cut OEM SEIC wire harness, on the driver’s

side just below the OBDII port. You will need to find the transmission

park signal, (blue with grey stripe wire).

□ Use a multi-meter to verify the transmission park signal. Turn the

key to the IGN2 position, (do not start the truck), as to supply power

to the dash display. The resistance should read close to 0-ohms in

park and open circuit in all other gears. If this is correct, put the car

in park and turn the key to the off position.

There are multiple blue wires with various coloured stripes. The

transmission park signal needs to be electrically verified with a

multi-meter to ensure the correct wire is read.
