Mercruiser trim limit switches

[itsneverfinished]

Hey all. I need a little help. I have a 70s era 255 tr2 outdrive on my boat. I replaced the trim switches on the pivot pins. I was going to wire them as it was, but like most wires in my boat the went nowhere. Corroded and broken. I nEed to figure out how they are wired to the pump, more important is the trim limit. It only currently trims up with trailer switch depressed. It has the vertical 3 pushbutton panel. I can figure out the indication switch, at worst run new wires. That's not that big a deal.
Thanks,
Brandon
