a little wiring help please...

I have a '73 240Z and took the motor out to replace it and while I was at it stripped most of what I could out of the engine compartment so I could paint it. I pulled out the front wiring harness and managed to get most of it plugged back in last night. I am left with three green wires under the dash and I know they hook up to the horn relay (according to the shop manual) but I can't determine which goes where from the manual. There is a sold green, a green with a red stripe and a green with a black stripe I believe. The relay is marked with 3 letters one for each terminal, I do not have it in front of me so I don't know the letters off the top of my head.

Can anyone tell me which wire goes to what terminal?

Thanks,

Craig

Green goes to H letter for horn
GR goes to B for battery - middle
GB goes to S for signal.

Edit for error on letter B! lol I missed sesame street
