Help with AC wiring after sleeper swap 94 379 Pete

Can someone help me with sleeper A/C wiring. The A/C blower in my bunk isn’t turning on and I'm suspecting it has to do with this extra harness connector.

I have a 94 Pete 379. It originally had a standup unibilt 63” sleeper. The a/c in my cab is air operated and the cab to sleeper wiring harness has 3 connectors.

I recently replaced the sleeper with a 48” unibilt flattop from a 95/96. This is the year I believe Peterbilt stopped using air operated A/C and moved to electric controlled. This sleeper has 4 connectors. 3 out of the 4 matched with my harness from the cab. All the lights and speakers in sleeper work except the a/c blower.

I have an extra 2 prong connector that I’m not sure how to wire.

One wire is B239 which I’m assuming is a ground based off the wiring schematics I’m looking at.

The other wire is A495 and I’m not sure what it should connect to.

I’m having thoughts that maybe it’s just a simple power and ground wire but want to be sure before I cause any troubles.

I have the Peterbilt wiring schematics for pre 05

 

Won’t work for this application. Old sleeper was a 63” and this one is a 48” complete different A/C setup with the vents. HVAC control panel is completely different also.

 

I did solve the issue though. The extra harness with 2 wires is simply a positive (495) and negative (239).

I spliced it into the accessory wire that controls the 12 volt plug right above the a/c unit. Put a 20amp inline fuse for added protection and the a/c blower motor turns on and works fine now.
