Just noticed that the license plate lights stay on even after you turn the ingnition off (and take the key out). Aren't these supposed to bewired to the curcuit for the lights? The only other work that was recently done was a new radio install, but I don't think that has anything to do with it. Let me know if you guys know what to check. Will have to check the wiring diagrams on the W124 repair manual CD. Also have a digital multimeter but am just not that great at troubleshooting electrical yet. Car is my 300TE wagon. Thanks for your help.
