1981 Harley FLH wiring harness question?

I am rebuilding an 1981 FLH. My question concerns the wiring harness. Coming off the starter relay there are four wires. Two are black ground wires, one is green going to the solonoid and the other is orange(pin 87) that is supposed to go up to a copper stud under the instrument panel. The previous owner just had this orange wire running straight over to the copper bar off the battery. The bike ran fine for years like this so I assume its ok. I was just wondering if anyone can tell me a little more about what the orange wire is for?

Answer:

I also have an '81 FLH--- welcome to the elite club-- the orange wire is a power wire to the relay, mine is hooked to the power side of the main circuit breaker, same as the wire to the ignition switch. Also if you are re-wiring w/o diagram, make sure the power wire to the start button goes thru the neutral switch or the bike will be able to be started in gear---trust me thats a problem waiting to happen. Just found what I was looking for earlier--The relay has numbered contacts---No. 1 is the power wire--No. 2 goes to the solenoid--No. 3 goes to the start button--No. 4 goes to ground
