I ordered from Hondadirectline a spoiler for my GL 1800. Unfortunately I did not get a template in the box with the spoiler. I've heard from others that maybe it's not needed? Also, I have a Back Off Brake light modulator. I see that Electrical Connection sells a harness for the spoiler light to make the spoiler light a running light http://www.electricalconnection.com/wire-harnesses /hrns_gl18spoiler.htm. Although this is made for Kisan Pathblazer taillight modulator (model 200GW), wondering if anyone has used it with the back off modulator. Any help greatly appreciated including pictures and diagrams! Thanks!
