This weekend i finally installed my new gauges. I ran power for the EGT gauge to the backside of the fuse for the accessory outlet and i ran the gauge lights to the back of the fuse for the instrument illumination. Now i don't have any lights in the dash, no power mirrors and no radio. The power seat and fan blower still work though, as do exterior lights. I tore the dash back apart to check wire connection and cannot find any obvious breaks. Is there another fuse or something that i'm not seeing?

96 12v. not stock

 

Check the IOD fuse in the fuse panel in the dash. In my 2002, it has a plastic clip over the top of it.

 

Similar issue. I installed a new aftermarket radio about 3 weeks ago. No issues. About 2 weeks ago, added an egt/boost in my 96 12v 5spd. For a few days, no issues. One night, no lights on the gauges. Instrument fuse is fine. I replaced the head light switch, no change. Radio works, headlights work fine as does using the head light switch to activate the interior lights. I checked my wiring, and all is still secure and not shorting out. Power for the EGT is pulled from an add-a-fuse off the radio circuit.

Thoughts? Did I miss something?

 

check your fuses in the truck, check your grounds
