Horn wiring help

[PeeBee]

Guys, have managed to 'lose/delete/remove whatever the cable from the horn relay to the horn. In fact i had removed the horn completely so wanting to reinstate it but cannot for the life of me work out which of the 3 wires from the relay connects to power the horn. I can hear the relay click when the steering wheel is pressed, so I have 3 wires, a thick green, a thin yellow and a thin yellow/black. I cannot find the wiring loop for the horn in the hard copy manuals i have, but am looking in the RD28 supplement only. HELP appreciated so i can get this bee sting of a job sorted - brain is fried! Thanks in advance.horn wiring.JPG The red wire goes to the horn

OK, the plot thickens. I found this wiring diagram in the manual. It looks like the green white is the one to cut and join to the red to the horn. nup, nothing when horn button pressed. Checked the fuse box under the dash, and found 2 blown fuses, but funny enough they were not on the engine circuit fuse - like WTF is going on. I have jumpered direct from horn to the pos on battery and the horn works. Prior to cutting the green white I could hear the relay click when the horn was depressed, now nothing. C.JPG
I am only running one of the two horns - can't find the other one - would not think this matters?

Sorted. Have to take offense with mr Nissans colour scheme though. The cable noted lg/w is plain light green, and the cable noted as Gr is light green white. Anyway, thats 2 hours of my life i won't get back, but its done, I HAVE FOUND MY HORN!!!
