Hey all
Does anyone have the under seat( YELLOW) harness pin assignments for 2019 Ram 2500 Laramie trucks(assuming 19 classic as well). Looking for pin assignments. To my surprise, the driver and passenger differ and they re NOT the same as 13-18 trucks. Threw me for a loop.

Thanks!

Thanks guys- ended up finding it. Stupid thing couldn't be named anything like "passenger seat harness" or
"passenger power seat plug" like the
driver's side plugs.
Instead,XY412A seems more fitting to FCA haha

Is there also a free pin on the mating side of the other side of the connector?

The connectors.dctools link is very detailed and easy to use, at least when it connects. I'm not familiar with using the link GT posted.

Try the following link.

I am posting for future reference for anyone looking for a replacement pin on this connector. I had a wire pulled out and it took me hours to figure out the connector P/N and the pin P/N. There are a lot of cross-references to these numbers, but this connector appears to be a Tokia Rika 4G2410-000 with 2.3II and 4.8 Terminals. Cross references below:
Connector
Yazaki Series 090II+187U-24P Hybrid Unsealed (7282-1248)

Terminals
Yazaki 090IIU-PIN2 (7114-4021) for 20 Smaller Sockets
Yazaki 187U-PIN2 (7114-4031) 4 Larger Sockets
These Terminals P/N are for 20-16 AWG Wires and I did not verify what wire the larger sockets had, but that will at least point you in the right direction.

Updating my post above:

the 090IIU-PIN2 did not fit in the socket I needed, I ended up having to get the 090IIU-PIN1. Check your wire size on the Mopar connector site above for your specific pin*
