Procedure 1: Install the Harness Cable
CAUTION: Always use safety stands when working under a raised vehicle. Never
work under a vehicle supported only by a jack.
Note: Make sure the harness cable and adapter cable can reach the DriveRight con-
sole mounting location before making the following connections.
Locate and Tap VSS Wire
1. Locate your vehicle’s VSS wire.
You can find the location of your VSS wire at the website for Ros-
tra Precision Controls: www.rostra.com. Click on Cruise Control
and then click on “Search Application Guide.” Enter the year, make
and model of your vehicle. The search results will include the VSS
wire location and wire color. There are other links to the Applica-
tion Guide and the path to it does change from time to time when
they update their website.

Note: Some base model vehicles with manual transmission and no cruise control may
not have the VSS module installed. Also, vehicles manufactured before 1992
may not have the VSS signal. Consult the service department at your vehicle
dealership if you are having trouble finding the VSS signal. If your vehicle does
not provide a VSS signal, you can install a DriveRight # 8126GD or a DriveRight
#8126HD model, both of which include a reed switch-based speed sensor that
you mount on the drive shaft or CV joint hub.

2. Tap into your vehicle’s VSS wire with a T-Tap disconnect. Use
either a red or blue T-Tap, whichever fits the VSS wire best.
3. Strip the white VSS harness cable wire 3/16”- 1/4” (5-6 mm) and
crimp on an insulated male disconnect.
4. Connect the white harness cable wire to the T-Tap.
Connect +12V DC Power and Ground Leads
DriveRight requires an unswitched +12 VDC power source.
Note: The wire used for power and ground connections should be 22-18AWG or have
the same diameter as the red +12 VDC wire with fuseholder.
1. Locate an unswitched +12 VDC power source:
Make a direct connection in the fusebox (recommended) using an
extra accessory slot in the fuse box or using a fuse tap connector
(not supplied). Or, find a known circuit that does not involve safety
