Re: Adding Tilt/Trim Switch
I put in an extra switch on the transom using a prewired connector/harness assembly and switch from Mercury. It was very easy. It would have been much more difficult trying to figure out which cable bundle to open up and guess which wires needed to be spliced into, especially leaning over into the cramped engine compartment. Well worth the $60, at least in my case.
Mine was part number 87-815200A02, depends on your year/model etc.
Good Luck!
