Does anyone have or know where I can get a diagram of what specific lights on the instrument cluster of a '98 F150 light up during the diagnostic checks when you turn on the accessory power? I need to finish my LED conversion but I want to make sure all my bulbs are in correctly before I bolt everything back together.


I also want to know if anyone else has had a light come on after the conversion and stay on. My battery and my airbag light are staying on but not completely on. They are really dim but still on. When turning on accessory power they light up bright and when the checks are done they dim out. They do not flash or anything so they are not codes and I am not running any codes. They just stay on really dim. What could cause this?

 

I would check and see if your alternator is charging enough, and if it is, check the plugs and connectors in the cluster and make sure they're making a good connection.

 

My alternator is good to go. I didn't have time to get at the cluster today but I will tomorrow and clean off any connections and re-check fitments. What specific lights are supposed to light up upon turning on accessory power and which are not?
