That's amazing. Yes, about a year ago I drove through some water and immediately the charge light came on (luckily I was a mile from home) I limped home and had to replace alternator, battery, and starter. Now that you mention it, I think it did start right after that, occasionally at first and now every time I drive.

For the 4x4 light, I have the manual shift case, I think that started around the same time.

What is the MPLS?

Also, I checked my Haynes and don't see a grey/red wire in the diagram and I don't see it in the engine. Where does this wire run? What's the best way to test it, measure voltage on it with a multimeter?

I really appreciate the help.
