Pop,
I wish I could help you but the my entire Illumiglo experience has been total confusion, though the final result is FANTASTIC:
1. First I ordered the faceplates from bluegauges.com, but in subsequent emails/calls bluedude wanted me to send my gauges to him. He never could explain why this was necessary so I canceled the order.
2. Next I tried to order them from StreetRacerParts but the girl said they no longer carried the 220mph white to blue model, even though they are described on the website @ $89.99. I called a month later and forced the issue; finally she found the gauges and I ordered them without the digital inverter.
3. The gauges arrived with a control switch....surprise at no extra charge..... which, judging from your exchange with nitrousjunkie, sounds like a digital inverter. This switch has a dimmer plus a color changer so you can go from the beautiful robins-egg blue to an ugly aquamarine........why? but I'm not complainin'.
4. The gauges that both SRP and bluegauges carry are the same...Illumiglo, but I think that bluedude makes his buck on upgrading the setup somehow, hence his persistence in wanting the customer to take his bike apart and ship his gauges to him....... no friggin' way!
5. I had my dealer install the gauges and the control switch/digital inverter?. The boys mounted it above the clock laying flat, facing away from me so the wiring can enter the cluster at the top and be totally unseen. It looks like a factory install. But I don't know the particulars of how they wired it.
6. I'll send pics as soon as a) it stops snowing, b) I clean the bike c) my wife teaches me how to operate her digital camera.
7. If we're talking about two different things............as Emily LaTella used to say on the original Saturday Night Live..........never mind!
