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 RUN 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.
□ Mark transmission park signal wire for connection later in Part 5:
Installing the Control
Components.
□ Disconnect batteries (both driver and passenger side).
□ Drain coolant from both the primary and secondary radiators
(drain for primary coolant is on driver’s side, secondary coolant is
on passenger side). Start with the secondary radiator. Save
coolant to be reused later. Close drain caps when coolant has
been drained.
