I didn't catch there were two relays in question. My info was for the old school one seen between the horn trumpets. Does not matter where these items are mounted really. A stock style configuration would have horn trumpets up front, one on either side of radiator. One would be marked "High Note" and the other "Low Note" for a harmonising toot. One relay will suffice. Wired as I said for the OG type and as per instructions on the solid state model.
You say you don't understand why there are two relays. Are you saying one is installed already between the horns by a PO and the other came in the AAW kit? In that case, you do "have" two relays. AAW does not know if a person already has one, or if they do, thay may want to switch to solid state.
Let us know what happens, be sure the hot leads to horns is fused.
