I will get a photo of the connector soon, but you can get an idea from the black receiving end of it located on the horn in one of the photos. It didn't look like the kind of clip I could purchase, rather it had some shaping to it. The wires went into a larger loom intersecting from around the area, and the steel bracket itself had some sort of recess to where it attached to the frame. Seen together under the years of matching corrosion, had a stock appearance. I'll check the group, thanks!
