Probably should have seen that coming

got the new car stereo, wiring harness and trim kit from Amazon.

Matched all the wires together, sealed them with heatshrink tubing, plugged the harness in…. nothing.

Took it out, double-checked all the wiring, Googled a bit to see if there was something I was missing, put it back in…. nothing.

So now I’m gonna have to go somewhere with my tail between my legs and say “Can you install this for me?”
