John:
Great work!
My layout is small enough that I have no real need to lower or raise the liftgate when I am inside, but you have solved the problem for those that do.
I was able to tuck the yellow controller under the I-beam next to the liftgate:
I am wondering how many out there are going to follow your excellent example that you provided with diagrams and instructions and do the same.
Thanks for posting!
