Where is horn relay and lead to horn? 91 Jimmy

[flyloki]

PO put in cheezy horn button on dash and new horn/wiring/relay in engine compartment, and I'm attempting to fix it correctly.

Horn fuse was blown and I can't ID horn relay, nor find the OEM leads to horn, PO probably snipped them some where. I do see a small relay board just above and left of gas pedal. On left side it has a squarish white relay on top a round metal relay just under it and open area on the right. Can't really see where the wires that come off it are. Any ideas?

Also when I swapped my steering wheel I was attempting to turn and pull out the sleeve that holds the spring /horn contactdisc/wirelead, and broke half of plastic sleve bit that retains it down in the hole. Any suggestions on how to glue this?

Thank you,

JB

Chevy blazers used a funky horn relay that is hard to find nowadays. It is a three spade deal and usually flops around on a pigtail above the fuse box. I know for sure there is a green 14 gauge wire going from the relay to the horn.
I have a bunch of 73 and 74 harness here. Let me go check the other wires.
GM is pretty good about keeping the same color code for there wiring.

Well, I just checked out a couple of harness I had. Granted, it's possible that GM changed the color code thought out the years. but for 73 to 74,
to the relay,
Red 12 gauge, 12+ power. This could change.
Green 14 gauge, to the horn. Should be standard though out the years.
Black 16 or 18 gauge (can't tell) goes to the horn button. Could change to a green small wire in later years.
