I've searched the web and this site but not finding what I need. I replaced the number one circuit board in a 2006 Frieghtliner school bus with the Mercedes engine. Now the child minder and emergency exits alarm doesn't work. I kept the harnesses that plug in the back separated as I took them off and replaced the fuses and relays correctly. Trying to find a diagram that shows the plugs in the rear of the board that would show which harness controls the child minder and emergency exit buzzers. Any help appreciated
