Well I can offer this evidence. Recently installed daeos harness and wired to the red/white lead in the fuse box. I was all happy until the trio of indicators lit up a few days later. My indy said there were many electrical-related fault codes present, but found no problems with the transfer case. He suggested I find another way to power the daeos harness as that dme is very sensitive.

This weekend I was attempting to use a "add-a-fuse" tap device on the 10amp fuse to power the daeos, and as soon as the key turned the three lights came on again. Obviously the electrical system doesn't like my wiring changes and is detecting a problem.

It could be that one of my wire taps isn't clean. Just no idea but thought this might be useful info.
