I just installed a Pioneer DMH-WC5700NEX using a Maestro RR and am wondering what some of these "extra" connections are for. I've searched for some schematics but am not finding what I am looking for. They don't seem to be necessary for what I'm doing, just curious.
Going back and looking at the stock radio... turns out the smaller 4-wire one went to the part mounted to the trim piece. It isn't needed with the new wire harness adapter. Still not sure what the other plug's purpose is.
Following this one. About to install a K150 kit in my 14 and kind of nervous with all the wiring lol. Hope I don’t screw anything up!
It was actually pretty easy. I bought the radio from Crutchfield and it came with everything you need. I had them make all the splices for me for about $25 which is SO worth the money. Back when I first started buying/installing radios in the 80's, there were only a handful of wires to connect and it was easy to figure out. Let's just say there are a LOT more these days.

thats good to hear. I just ordered a headunit through Crutchfield as well, I found a dash kit on eBay and everything is pre spliced as it was used so that’s good. The only thing that worries me now is what he spliced & if it’ll match up to my headunit. Do you know if there is any difference between what wires need spliced together to correspond with different branded head units?
Stereos generally have mostly the same wires, often in similar colors. But auto makers do not follow a pattern with their connectors. That's why Crutchfield is so great, they match them up well so you get the correct adapter harness for your make of vehicle, and they provide good instructions to match wires. The extra cost to have them splice it is just so you don't have to do the work. If you know how to solder or crimp and have the tools, it's easy enough to do yourself.
