Replacing The Keyless Entry

The OEM keyless entry systems in older Winnebago’s are starting to fail and the equipment is no longer being manufactured. Winnebago has identified a replacement system and designed an adaptive harness to facilitate retrofitting the older SCS equipped coaches with the new module made by Tri-Mark

Here is how the retrofit played out on my 2005 Journey 39K. I should point out that this coach is NOT equipped with a remote keypad.

The SCS Module on MY coach was P/N 151458-01-000 (earlier coaches may have another part number). To replace THIS module with the Tri-Mark module you will need the following parts: P/N 176367-01-000 Tri-Mark Keyless Entry & Cargo Lock System; P/N 176356-01-000 Wire Assembly Keyless Entry & Cargo Lock; and P/N 063912-02-000 Relay (Two relays are required, but you will reuse the one attached to the original wiring harness).

On the 39K, the SCS module is located forward of the dash beneath the large plastic cowl. When the cowl is removed you will see the module mounted face up in the forward-left portion of the opening. It is held in place by to screws.

Once the two screws are removed, lift the module free of the dash area. Identify the connectors (2) at the end of the short harness and disconnect the module at those connectors. These connectors are where you will connect the new 176356-01-000 harness.

Now detach the 063912-02-000 Relay that is a part of the OEM harness.

The two relays are then attached to the new 176356-01-000 harness, and the harness attached to the 176367-01-000 Tri-Mark module.

It is then a simple matter of connecting the harness to the connectors below the original module’s mounting position and routing the harness to suitable mounting position for the module.   

Enough harness length is included to allow flexibility in locating the module in various coach models. I just fastened the module to one of the previous module’s attachment points.

This module came with the remote fobs pre-programmed, but to program additional fobs there are a button and LED wired to the module. I left these bundled as shipped, but if you anticipate reprogramming in the future you could route these to a location accessible when the cowl is in place.

At this point I successfully tested the installation and then reinstalled the cowl. Total time, working slowly, was about thirty minutes. The only tool required was a medium Phillips Head screwdriver. 

We are now back in business and can unlock the door or storage compartments from three campsites away!
