Rear Heated & Ventilated Seat Connectors

[brental1]

That setting should be programmed or not programmed. Mine is defaulted to not programmed

I see that setting now. Changed it to Programmed; but still have only Left side switches working.

Well that is progress

For sure. I feel somewhat optimistic since the controller is in the left side seat and at least it's communicating with the right side. I'll trace the console harness tomorrow. Can't imagine it doesn't split A207 and LIN BUS to both switches.

Incidentally, there's another circuit in XY360A that's not populated. Pin 13, A195, RD/YE, Fused B+. I wonder what that's for?

A195 is Fuse 42, here is what I found for fuse 42:

42A&B

10A

Mod Transfer Case Switch Module (TCSM) / SBW / Electric Park Brake SW / Module TPM Trailer / Module Gateway Can-C Trailer TPM / Seat LT & RT Vent

A195 is Pin 25 in:
ASSEMBLY-POWER DISTRIBUTION CENTER-INTERIOR C1

Where is this connector located?

Thanks.. I don't totally understand all of them; but doesn't seem like there'd be any value in running this wire to the center console plug (for future mods). The connector, and same description except C2, plug into the Interior Fuse Box..

Today's update, and to help my thinking. There is 12V at both the Fused B+ and the LIN BUS pins of the Left seat switch connector. With reference to ground pin in the connector, so apparently the ground is good. I think the LIN BUS is supposed to be around 12V when resting, and sends out a square wave when working. I even verified that the connector was properly pinned . I have another seat that is heat only. I used the controller from it and got heat (only) on right seat and still nothing on left. So, it seems the only thing left if the Left side switch. Strange because both switches are brand new. I think next I'll try repinning the switch connectors and swap the switches..

 

[brental1]

Just so pumped that the right switches work! Have ordered another left switch; and hoping both sides will work..

It’s great. Would like to see a diagram with all the wires, connector names/numbers and connection points. This would make this a DYI for anyone willing to do the wiring.

I may try to figure that all out soon. I want to get the 360 camera retrofit done first.

See if you can read this one. Also, I have XY430 and 435 connectors, and pins for one of them.
I see it truncated some. On XY430A, Pin 1 goes to XY331A Pin 23, then to Assembly-Power Distribution Center C3 Pin 32.
Pin 9 goes to XY331A Pin 54, then to Assembly-Power Distribution Center C3 Pin 35..
Pin 10 is spliced to PK/BG (4 branches, 2 to Front Seat blowers and 2 to Rear Seat blowers)) at XY330A Pin 1.

I upgraded my rear seat to the reclining seat (from a wrecked truck) and the one I replaced it with has seat heaters. My truck also has the wiring harness to the rear seats under the carpet. The console however does not have the proper harness to go to switched at the back of the console. Do you know the part number that I would need to the get the correct factory console wiring harness? I have a 2022 Laramie.

Thanks for any help you can give me.

I bought 74. It included the heated/vented switch connectors, two115V connectors, and an extra 12V connector..

Thank you for the information. I really appreciate it.

Finally found the connectors on Mopar Connection and it is indeed for heated/ventilated seats. Now to see if I can do the mod should be pretty straight forward!

Were these wires live already? Looking to splice into the PK/BN for a ignition switch source for my DC/DC charger. Didn't get a chance to probe with a meter yet.

Did you need to enable anything in the truck using Alfaobd?

 

[Carlmarinerepair]

Your 2500 is quite different than the 1500. The seats are different, HD Rams don’t have ventilated rear seats, and use a different rear heated seat module.
All HD Rams, regardless of trim level or options, are fully wired up for fully loaded front and rear seats in the body wiring under the carpet. The center console harness will not have the connectors for the rear switches, and the dash harness that plugs into the main center console harness will not have the wires for the rear switches either.

Hey Jimmy I know this is a older thread but I wanted to ask you what console harness number would I need to connect the rear seat switches in a 2022 ram 2500 big horn .I have heated rear seats out of a donor . And will this conversion work as I see you wrote about wiring in the dash harness not being present.and or can it be done. Thanks in advance Carl

Yes, I had to flash a few things to enable Heat and Vent rear seats

Was it just these settings?

Car configuration change: Left Rear Climate Seat Switch Present: ' NO ' -> ' YES '
Car configuration change: Right Rear Climate Seat Switch Present: ' NO ' -> ' YES '
Car configuration change: Rear Heated Seats Present: ' NO ' -> ' YES '
Car configuration change: Rear Heated Seat Levels: ' DEFAULT ' -> ' 3 LEVEL (HIGH / MED / LOW / OFF) '
Car configuration change: CRSM Comfort Rear Seats Module: ' NOT ENABLED ' -> ' ENABLED '
Car configuration change: Seat Material Rear: ' TYPE 0 ' -> ' TYPE 4 '

I didn't document the changes; and don't remember. The changes you listed make sense. I don't think I set Seat Material. What are the options, and what is Type 4?
