Upfitter Switches causing M/C problem?

[JBB1970]

I bought an Upfitter switch kit off of ebay yeaterday and before I did so called my local dealer to try and get them to match the price, They wouldn't of course.

However, the dealer said that they have been seeing problems with the brake master cylinder and people having to replace them because they installed the upfitter switches. He would not go into more detail than that.

Anyone ever seen a problem like this before? or heard of it? I could maybe see if there was a switch hooked up to the braking system somehow??

Any way it just seems a bit strange to me.

Thanks
