Installation Supplement

for Brake Controller Pigtail for Winnebago Class A Motor Homes built on Ford and Workhorse Chassis (2007 and newer)

Part #EC-4129

Date: November 1, 2006 (Revised October, 2007)

Use with Unified Tow Brake Towed Vehicle Kit (TV-1000K and TVH-1000K))

2007 and newer Winnebago Class A motor homes built on Ford and Workhorse chassis are pre-wired for supplemental braking.  This connector will allow the Unified Tow Brake controller to be plugged into the factory harness in the motor home so that the existing wiring can be used instead of running the Unified Tow Brake motor home harness.

Be sure the ignition is off during installation of the Brake Controller Pigtail.
