It has to be wiring or fuses.

Did you check your fuses?

Well, I guess there's a relay to check, too.

I'm no electrician, htough, I can only give you basic advice

hmmm....just a hunch, check the bulbs. could have caused a short and blown every bulb. Also check the dimmer it's on the left hand side close to the choke pull and the power mirror switch.

It could run correctly and still have a bad connection. Thats what mine did. On my trailing ignitor, the prongs were a little bit loose and making it to where the tach didnt work. I would clean and then give the female connectors a "little squueze" to get them tighter. Worked for me at least. Lights, I had the same problem and realized my dimmer switch was unplugged from the back somehow. I hope this helps somehow.

do al your externall ights work. Headlights, parking lights, brake light. I had a problem similar to this but a few differences. Let em know if your light work so I can type out what my problem was and how I tracked it down.

As for the lights, the dimmer may be shot; with a bad ground. Mine was. My dimmer is now bypassed to be brightest all the time.

I'm another victim of the bad dimmer. You can jumper the connection to the dimmer temporarily which will put full brightness of all interior dash and console lights to see if it works. (or do it permanently like ChasRX)
