Replaced the door accuator on passenger side anad when I reconnected batt I lost IP lights except Batt and CheckEngine. Research pointed to Class 2 Data linkks, and located an 11 pin comb connector (under left dash). Unplugging the comb restored the IP lights. Looking for a wiring diagram that show this connector to trace wires.

Hi and welcome.
Do you mean you replaced the passenger side door switch module? Have you tried just disconnecting that to see if it restores the lights? When you pull the comb and the lights work, this tells me something on the network is pulling down the network. If it's not the door module, then you would need to chase down which module.
Manuals with schematics are available here:

Sorry for detail ommission, I replaced the HVAC blend door acctuator, and even with it disconnected the problem persists. I've checked several of the manual links you provided (thank you) but can't find a wiring connection diagram to the comb connector that I have seen identified as both JX200, and also Splice Pack 205.
