Would a heated mirror have it's own hot line? Found this online, not an Ex but close.

If you are talking about the round three wire plug for the side mirrors, you have a common, a wire for the up/down motor, and a wire for the left/right motor. The adjustment switch changes the polarity on the common and motor leads to make the mirror move through it's motions.

Just to add, it's been a long time since I've tinkered with a 3 wire mirror, and every mirror thread I've posted in has led down a rabbit hole. Use this information at your own risk.

I'm talking about the rear view not the side mirrors.

In that case, I believe you have power, ground, and a signal from the tranny selector. If the mirror has darkened at night, it will clear if you put the truck in reverse so your vision through the mirror isn't hampered.

Same disclaimer as above still applies.

In my 2000, I had the 3 pin plug on my mirror. The gel went out so I found one at the junk yard out of an 04. It had a 6pin plug. I cut the harness and took it to compare with mine. The wires were the same, and in the same place, just a longer plug. So I had to cut off one tab and the 3pin plug fits into the 6pin of the 04 mirror and it all works. Hope this makes sense.
