I think thatat the handlebar switches you should have the Honda OEM wiring colors for the 1980 GL 1100 Standard and Interstate.
You will need to identify with an Ohm meter the contacts on the switches.
Light Green: from the ground side of the horns.
Turn signal colors:
There are two sets of contacts. You will have to identify them. The first set of three contactssupplies power for the(front and rear) left and right turn signal bulbs. The second set of three contacts supply power to the front position lights until the turn signal is switched. Switch left, left position light goes out; switch right, right position light goes out.
First set of contacts: Front and back turn signal bulbs.
Gray: Connect to center contact. From the turn signal relay for power to left or right
Orange: To left side, front and rear, turn signal light bulbs
Light Blue: To the right side, front and rear, turn signal bulbs
Second set of contacts: Front position lights
Brown with White tracer: Connect to center contact. Power to front Position Lights until switched.
Orange with White tracer: To left side front Position bulb
Light Blue with white tracer: To right side front Position bulb
You didn't say anything about the Headlight Dimmer Switch or the Clutch Switch located on the left handlebar. I can give you the wire colors if you need them.
Good luck and let us know how it goes.
