2011 GC - A/C Climate Control Unit Upgrade question

Oh yeah, I should've clarified, I meant to specify if that part number would work for the connector/pins. Sorry about that! I'm personally going to pick up a compatible sun sensor at a u-pull-it to both save myself some money, as well as to reduce e-waste.

I would take the connector/pins as well for the sun sensor. But, from what I've read, messing with the sun sensor connector is a real pain? I'm trying to plan out what to do here, and if I could get away without spending $34+ dollars for that, I definitely would.

Also, thank you for providing the sensor part number!



And those look good, I'll have to get myself some supplies, including the soldering iron.

Ah okay, yeah it works for the pins. It is a bit of a pain to cut and solder the new sun sensor connector, because the wires are usually very short so you'd probably have about 1 inch max from the connector to the lowest point you can cut the wire at. Still plenty to work with. I cut the 4 pin connector, and then cut the 2 pin one from the vehicle I'm working on and solder the 2 existing pins, to the new 4 pin connector, and solder 2 extra wires to the inner pins and run them to the HVAC, where I solder those to the pins on the ATC connector (which weren't present in the manual version). I am aware you can de-pin the sun sensor connector for the 2 wires your van already has, but with the little room there is against the windshield, it's just faster for me to cut and solder.

Edit: the part number isn't very important, what is important is the sun sensor itself which should have 4 pins inside. For 2011 they decided to budget cut, and the vans equipped with auto climate controls and no auto headlights only have a 3 pin sun sensor. I realize you're adding only auto climate controls but should you decide to do it down the road, you will already have the correct sensor.
