I had posted a couple of weeks ago that my brake lights on my 2007 Monaco Dynasty Emperor IV had went out. Turn signals, running lights, backup lights, engine brake, and cruise control all worked. After pulling out the wiring diagrams, checking every relay, fuse in all the run boxes, I traced the problem to the PCB #2 in the Rear Run Box. Was lucky to find a surplus NOS PCB #2 on the internet for about $150 and it solved the problem. Learned a lot about how the brake system and lights work. Hope this might help someone with similar issues. Reminded me of flying the MD-11 with the glass cockpit. We were always going, "What the hell is she doing now?" We have renamed our Coach, "Miss Christine" after the movie. Those who have watched the movie will get the idea/picture. Have a great weekend. Joe
