Hi, This is my first post, but I was wanting to know if I have a 98 Deville Base. No bose, no amp, no center speaker. After the installation of an aftermarket radio, I have already went through two batteries. Upon research I NOW see that a data harness is needed. But which one?

also, for some odd reason the power windows continue to work even though the car is cut off, and the keys are removed. Even after the doors have been opened and closed.

no009limit, welcome to the forums!

Just curious, will the gmos-03 fix the retained power cutoff?
