A tip. To get the switch blank out, that I did, I ended up pulling out the top of that part of the dash - need to pull the hard plastic piece off to the top and left as well to do that. However I don't think that is necessary - having now got the blank out. I think it is possible to get a...

IMO. There is a technical answer, which is, it looks like the wiring harnesses are the same, so it is relatively easy to add an after market brake controller, if people want. This is great for us that need to - for various reasons I could not wait for an ideal vehicle. However it is probably...
