OK, that looks to be a 1980 85hp with a later midsection, the trim motor appears to be the two wire unit: (one blue/one green). The junction box is the correct one for the two wire tilt motor with the two relays. Unfortunately, someone had cobbed up the wiring quite badly. That junction box was used on the later model engines and should be mounted on the exhaust cover. Unfortunately, this early engine does not have the mounting holes for that trim relay box, and someone has tried to extend all the leads so the box could be mounted inside the boat….
Here are the pictures:
It should be noted that BOTH relays must be working and in place for this system to work in either direction. In other words, if you pulled out the up relay, the unit won’t work in either direction. If it were mine, I would fashion some sort of bracket so that later style trim relay box can be mounted onto the exhaust cover, then properly shorten and repair the leads.
