First, thank you for any help that I get. I am installing an after market stereo. I am pretty sure I have figured out most of the wires, but there are a couple I am not sure of . Those 3 wires, any idea what to attach to? Thanks!

Hey all, wanted to pick the hive mind on an issue I'm seeing with my 05 avalanche, 180k miles. It appears the 4wd transfer case is leaking fluid from the rear output shaft seal. My mechanic is going to look into it more tomorrow, but I'm wondering if anyone else has had issues with these...
