I can’t remember exactly which one I purchased. I believe it was off of an evinrude. I bought the trim switch tiller mount, and switch/wiring harness assy. I couldn’t do it the way it is outlined by the previous post, so I just taped it to the end. Ran the wires external and into the cowling. Works like a charm!
Eventually the electrical tape starting working its way behind the mount, so i removed it and used small pieces of aluminum wire ran horizontally on the tiller throttle handle and tilt switch mount, then taped that together. They act as a splint. Call it what you want, but it works! Lol
My handle grip is not hollow, the aluminum roller portion goes all the way to the end of the grip.
