90 Mustang GT. When I turn on my headlights they work fine along with the fogs. But my tail lights do not illuminate unless I press the brake pedal. Also the gauge/instrument panel lights stopped working. Kinda need both these things to function if I plan taking my girl out tonight! I checked the headlight switch connector (http://www.latemodelrestoration.com/item/LRS-14489A/87-93-Headlight-Switch-Connector-Assembly) as some other threads and other forums have said to do. It was fine. No burns or anything. Not sure what else it could be. I'm not very savvy with electronic wiring. If anyone has any ideas or areas to check I'd appreciate it. I'm home all day today so I'd like to tackle this problem.
