Mine is currently stuck at Mira Loma as well, 4/3 build week. Been stuck there since 4/29, hoping to get it soon..so close yet so far. What dealer did you end up going with?
Still waiting on my harness myself but the male side should be the plug that connects to the audio module which would be where the signal is coming out from.
The female side should connect back to the factory harness and is where you would splice the amp outputs back into if you were to reuse...
