INSTALLATION INSTRUCTIONS


 

My system works fine but I want to upgrade the system to avoid a problem. Can you tell from my VIN if I have an early or late 1995?

What generation system is mine?

What parts do you recommend be proactively replaced to ensure the system is reliable?

Steve,

This is a later model 1995 and would definitely benefit from our US21 switch kit. I would actually recommend the US22 kit in your case since it would come with an updated relay and steel bushing adapter for the pump switch. The only other failure prone part at the age of your coach is the actuator which can be replaced with part# W8000504N.

Description states lifetime replacement for original purchaser but the instructions in the PDF say there is only a two year warranty. Which is it? ( Richard, 07/04/2016 )

Richard,

We apologize for the confusion. These DO have a lifetime warranty. We will be changing the instructions to reflect this, thank you for pointing it out!

Will us21park brake pressure switch fit this viv number

( Raymond E.Parent, 07/15/2015 )

Raymond,

Yes, your VIN indicates that you have an electric park brake pump so the US21 would be the correct kit to replace both the Rotten Green Switch and grey switch at the actuator.
