I am installing front power/heated seats out of a 2003 Avalanche from a junkyard. Both it and my truck have the al0 rpo code for passenger seat sensor. However, the new seat does not have the 2-wire connector. (Pink and tan/black). My original seat base does. The new base has the module bolted to the seat but no connector. So, I’m assuming it’s just a different style system. Can I add the wires into the new seat from my old seat base and have it work? VIN from the avalanche is 3GNEK13T73G176336

Without looking at these diagrams it is hard to know for sure which circuits you are looking at but what I would do is go back and get the connectors out of the Avalanche so that you can use them to connect to your vehicle.

Basically, we need to be able to connect to the module because I think these are close enough that you will get them to work using your vehicles switches and modules. You will just need to splice together the proper circuits so that this seat gets what it needs. However, you will not do that if you don't have the modules connectors for it.

Here is a video and guide that will help with this wiring swap:

Below you will see the wiring diagrams for each vehicle. The first is the Avalanche and the second is from your truck.

Please run through this and let me know what questions you have.

Thanks
