Trim down and wiring questions

[Presser150]

Installed force and some new graphs so rewiring my 94 190. New wiring was the easy part, now on to the old stuff. First, my trim down isn’t working, currently the switch on the throttle is the only one working, but only the up works. Pretty much the only thing currently working other than starting. Pulled the handle apart and looked at the switch, wiring seems to be intact. My only thought is to replace the switch or try to find the relays. Any other ideas?

Next, when I connect these wires to the battery, the trim quits working completely. No idea why or what these wires are even to. They come out from a hole in the fiberglass in the back right corner of the battery compartment. Any ideas?

The nav lights also aren’t working, no power in the back and only the green wire has voltage in the front, not the orange. I’m guessing I’m just gonna have to rewire the hole thing cause probably a bad connection somewhere.

Last question, any idea what this circuit board is to or is needed for? Up under the console

Sorry, forgot, one more. What is the headlight switch for? Not on the console, to the right of the driver seat. Or is that something a previous owner installed?

Thanks in advance

Can't help with the first two but picture 3 is a circuit breaker for something. Picture 4 is the livewell timer. More than likely you've broken the splice from the throttle trim to the bow trim switch and pulled a power wire off of the dash or tripped a breaker.

Thanks. Live well timer definitely makes sense.

The first three pictures are all the same wires, was just trying to show where they are coming from. They are the ones that when I connect them to the battery, the trim stops working completely. Currently have no idea what they are to

none of the fuses I have found are broken

Definitely looks like something added by a previous owner. You really need to run the other end of it down and see what it connects to.
