Quick Q Horn Circuit 78 GS550E

[Jedz123]

In the title.
Looking for the wire color for the horn switch. I believe the ground is very poor (someone hacked the main harness and has really odd wires "spliced and cut". I did my best to clean up the loom, have really good grounds but the left switch seems to be lacking a strong ground? Everything works but the horn and when I eoress I see a votlage draw from the Orange green on the horn side of .2V. the the orange green shoes a strong 12.8V when gorunded out through my voltmeter. Just the switch circuit is very weak. Cleaned the switch and contacts, notta, makes me think poor ground or poor circuitry. If someone could just show or tell me the horn circuit wires that would be great. I'll keep digging through the search feature.
Best,

On my 650, a green wire runs from the horn button to the horn. The orange/green at horn is always hot (with ignition on) and waits to be grounded out thru via green wire thru horn button to black/ white ground wire

Excellent and thank you for some insight! I have deduced that I have the same wiring on my 550E. Seems like the loom itself has a poor grounding circuit. the harness was hacked up and I found all sorts of odd wires spliced into the green horn wire.
My very best,
