I most certainly don't want you to think that I am unnappreciative of your help. It is most gratefully accepted. To be honest, I wasn't expecting such an enthusiastic response. I'm a member of some other forums and typically newbies are not as well received, so the feedback I 've received is with gratitude. I mean no disrespect at all.

I am a licensed mechanic (since 1998) but I am no longer working in the field full-time. I am also a mechanical engineering technologist, and currently working on a shutdown, which eats up about 12 hours of my time, 6 days a week. So, time is not something I have in any abundance until the end of February.
The reason I was targeting the lights on the overhead console was because this was likely the reason for the previous owner's dead battery issues, and I have a battery charger on the system full time at the moment, so alleviating that problem is just merely to eliminate that hindrance, and swapping the consoles is something that will take up very little time. I do not have the luxury of a garage to work on the vehicle, so my time is also constrained by the weather. That said, the temperatures here in southern Ontario this coming weekend look favourable to get digging into the JBE and FRM for some corrosion investigation. The reason I asked if the FRM adn JBE are VIN-locked, is because the vehiclke I am taking the overhead switch console out of, will likely have both a JBE and FRM modules as well. A used module is only $20 where I'm going. Just curious if they are interchangeable.
