I used a tiller trolling motor on a previous boat and couldn't reach the motor comfortably so I made a remote switchbox. It consisted of a momentary switch/button and a toggle stitch. 8' of soft stranded wire with clips for connecting to the battery, into an alum. box 3"x4"x2 1/2". The toggle switch lets it stay on constant or switch to momentary. 2 stainless 1/4-20 bolts with fibernuts are where the t-motor leads connect. workedd great and still use it when I put a tiller motor on my current for slow trolling. Will work on posting pics, but need my daughters help(I'm low tech).
I used an extension that u-bolted to the shaft for steerage, and frequently pushed it around with the rod i was fishin with.
