Yesterday I installed this modulator on my 07 wing under the seat by the relays. After hooking all wires all I had was one left side light bulb working and not modulating either. The horn wire didn't work either. One tech told me I need a two headlight system and another says I can't wire it off the relays only by the bulbs and that it needs a jumper wire but didn't say why or where. Anybody have any info on these? Are they any different then the Kriss posted here in the step by step?
