I have a 1987 Starcraft 161 for 5 years now. I am replacing the two Tilt/Trim relays (solenoids) and noticed that the red wire with the 20 amp fuse was hooked up but was not being used. I have attached pics to show that the harness from the relays has three prongs but the mating harness only has two prongs and no red wire going to the switches. The down trim and the Trailer tilt were working before the repair so I assume they are getting power from under my dash somewhere. Should I leave it alone or should I rewire to include that 20 amp red wire?
