Never mind seems that the yellow horn wire is the sugnal not the green....
Anyone have experience rience wiring in horns with relay? I can't seem to get them to work. 30 pin is direct power from battery for now all I have is a 7.5amp fuse not blown, 87 is + on horns if both horn terminals are on top of horn this is the left pin from what I can tell. 86 green wire going to stock horn. 85 grounded tried the stock black wire and also running separate grounds for horns/ relay attached to right pin of the horn connectoins are on top of that makes sense.
