I apologize if this isn't the right forum...

About a year ago I picked up this limo to replace an Expedition as an extra vehicle when we have a lot of family or friends visiting. It had numerous little issues that I worked out, but I have been unable to figure out how to remove the bar but mostly I I'd really like to have a wiring diagram. I'm replacing the CRT TV's with LCD and adding LED to accent the neon - which had dead power transformers. The LED TV's have a lot of visual noise lines when the car is running and I don't fully understand how the 2nd battery contributes. It was completely dead when I got the car and I have replaced it, but it didn't make any noticeable difference for any accessory. I know American Custom Coachworks is out of business and I doubt there are any professionals still using a 1994, but after hours of searching, I don't know where else to go. It's in beautiful shape and deserves to be fixed and updated.

Thanks in advance!
