I didn't even know about Charm - thanks! I noticed you had a ecomodder tab open on that screen shot as well, I used to frequent that site - back when I made a MPGuino for my saturn many years go. It's been ages since I logged in.

Thanks again for the Charm link - I just went to it - oh man.. what a life saver.

I think I found my problem - my ground splice pack was not under my speaker shelf... It was in my trunk. And it it probably in the nastiest part of my entire car......

That's the one spot in this wiring diagram I do not understand. If there are two separate 12 volt runs, what does the "c---k IP to body inline" signify? Are the two supply voltages not already separate?

Yep, that's the one I was referencing earlier.

G…K are locations in the connector. The third brake light and the rear brake lights have separate feeds from the front to the connector. After the connector there are three feeds, one to each light. My L is the same, lots of small wires in the harness. I split my brake lights and use them as turn indicators and brake lights when towing my L.

I had similar corrosion in the ground splice near my battery on my L.

Okay everyone - Op check good - 6 mile drive - all is back to normal - thank you for all the help! And now I know about charm.li - I cleaned out that cubby area in the trunk completely - scrubbed the rust down - painted it - put the now clean ground splice in a bag and zip tied it shut. That's not happening again.
