Installed a remote start with turbo timer and everything works great except that when it shuts down in turbo timer mode the instrumentation light stays on. All other functions work as described. Any ideas???

My Viper turbo timer keeps the marker and instrument lights on until it shuts off...normal operation for what I have. Do your lights go off after the truck shuts down?

I have a Viper remote also and my radio and interior lights stay on for 10 min after shut down, just like if you shut the truck off and didnt open the door.

Yes after shutdown.
10 minutes? I did not watch it for that long. My radio is aftermarket and hooked to the ign so it turns off, just the instrument lights stay on but I will test tonite to see if they go off after 10 mins.
