OK, I’m lost, don’t understand what you are describing…
How many wires does the trim motor have coming out of it, two or three?
Three wire motor: The black lead is always grounded. The blue lead is connected to battery positive (green lead not connected to anything) to make the trim motor run in the "UP" mode. The green lead is connected to battery positive (blue lead not connected to anything) to make the trim motor run in the "down" mode (opposite direction).
Two wire motor: Green lead is grounded and blue lead connected to battery positive to run the unit in the "up" mode. To run in down mode, blue lead is grounded and green lead is connected to battery positive.
Both of these types of trim motors require separate trim/tilt junction box harness in 1980. The junction box/harness for the three lead motor is completely different (just one conventional solenoid) from the two lead motor junction box/harness which had two relays in the box.
You can not connect either of these systems through the starter motor solenoid or you will be in trouble.
Post pictures of what you have if that will help….
