I have a trim toggle switch on the bow and one at the transom, the one on the transon stopped working going down only a few months ago.
Yesterday while fishing the motor started to trim up ll by its self?
It would not stop running so I pulled the wires out off the rear switch and it stopped, the one in the front does not work now so I assume they are switched together, the one on the throttle still works.
I figure I need to replace the rear toggle, where can I find this part?

You pulled too many wires loose. Separate the wires from the switch on the motor and don't connect them, then hook up the others. You should have a working helm switch. Then order a new switch for the motor.

The 85 motors didn't have switches on them as OEM, so you have a one off setup that may not have a lot of matching color codes. So just be careful.
