Steve again a fine job!!!!
But....being the homedad I am...I must ask a Q.....
In this photo there is an unused jack just under the grab bar mount.....
Whould it not be easer to punch the wire hole and grommet at this point and run the wire to that jack?????
Someone correct me if i'm wrong ...but that is the factory roof light jack....and it would save a few steps and it's prewired for high current......
You did say do the wiring yourself......just a thought....
