Looking to install an aftermarket stereo. I have the harness that says it's compatible, but there's one connection of the factory stereo that does connect to the harness I bought.

(Picture)
Green 1 and 2 fit in the Connection harness
Green 3 is the antenna
Orange 4 didn't fit in the harness and I'm not sure how to connect factory wiring to aftermarket stereo.
Blue 5 and 6 I'm not sure what their purpose is.

Can anyone help me out? Or share a document (I've hit a Google wall).

I appreciate the reply!
I feel like there is a lot of useful information in the diagrams you've attached. But I don't understand anything that they say. Is there a way to explain in a dumbed down version or is this something I should just take to a dealership to deal with?

Hello,

Okay, if I'm not mistaken it looks like #4 in your picture is the connector that provides power/switched power, ground, and all signals to your speakers. Where did you get your plug and play harness adapter and what kind of aftermarket stereo are you installing?

Thanks,
Alex

Hello again,

Okay, your new stereo does have RCA output jacks for your new amplifier, so you won't need run level line wires to it. So the rest (stereo) part of the hookup would be either get a connector to interface the new stereo with the OEM one or splice wires together from the OEM connector to the new connector. The wiring diagrams show what wire, wire color go to what speaker, constant battery+, switched power, ground, and power antenna(if available). I would run a fuse tap from your stereo's switched battery+ back to your sub-woofers amp's remote input. I hope this helps.

Thanks,
Alex
