Yea, cut wires like chuckford suggests.
And cut a few more just for good measure....

Your SJB is corroded.
More electrical problems to follow.

I think I will stay away from cutting any wires. Like I asked in my original post, what the heck is the SJB and where is it? More electrical problem huh? Not what I wanted to hear.

Ok I think I finally figured out what SJB is. Smart Junction Box. I love the Internet. I also found a diagnostic and testing procedure on PDF just for this issue. I am hoping it is either corrosion or a pin issue. I think I can handle either one of those. Here is the link if anyone wants to do some late night reading.

Search 'water leak" on this forum and see what it produces.

I think I may do that. The dealer called and said that the SJB is fine, but that the reverse light switch was bad. So they are charging me $210 to replace an apparent $49 part. Geez I need to get a repair manual and start doing this stuff myself.

^^^^ I tried to help. That's how they make their money. It takes like 30 seconds to change the switch...but the junction box must be the blanket internet answer to give. Despite new technology, the basic principles of car repair can still apply....reverse switches stick and you don't put roush stickers on non-roush mustangs. At least it'll be fixed though.

It just bothers me, because that is the only dealer I go to for my wifes Explorer and have been for years. Figured they would cut me some time. Anyway it is fixed so now onto other issues. I hope to have the car back to new shape soon. Thanks again!
