I had my Roush Supercharger installed a while back, but only recently was able to have the boost gauge installed. Since the Roush LED gauge isn't dimmable, I had the shop wire it up to be white during the day (no headlights) and blue (headlights) at night. It works pretty well since the blue is a lot more mellow than the white. Here's where it gets weird. The switching between colors ONLY works if I auto-start the truck first. During auto-start, the gauge is on (no key in) and blue. After I put the key in it behaves properly, switching with the headlights. If I just start the truck normally, I get a white gauge regardless of the headlights.
I'll be taking it back into the shop to have them fix it (hopefully) soon, but wanted to arm myself with knowledge here first. Anyone familiar with this and why it might be happening? I've looked at the wiring diagram for the gauge and it's pretty simple. Since my Roush shop installed it, I won't be tearing it apart myself to inspect the wiring. I'll let them do that.
