Thanks for that. crazy thing is those pin outs do not match mine at all.
A4 is my ground A2 and A3 are the power. Here is where i really get confused B2 B3 B6 B7 seem to be speakers i can get them to crackle is i hook the speaker wires to them. But there dont seem to be enough wires for rear speakers. is it common they would only come with front speakers.
I have a total of 9 wires 1 ground 2 for power 4 that seem make the front speakers work than one other i havent figured out it's roll yet.
This one takes the cake as one confusing install. not figuring out which is + and which is - on the speakers could prove to be interesting.

The cab only has two speakers in it from the factory. You can go to JDParts.com and get the breakouts and diagrams that will show were they are. You would have to add another pair of speakers to get four.

Thank you for all your help. I'll pick up a Vdub harness after work and get it wired in tonight.
Thanks again
Chad

Take a 9 volt battery to both wires for the speaker, if the woofer pops forward, then you have the neg and pos correct, if it sucks in, you have them backwards.

The wiring harness that you needed was the same one that is used for a VW car. Not exactly sure why JD used that, but they did. I took a pic of the plug and took it to Best Buy and the guy new exactly what it was and got me the adapter with the wiring diagram on the package. Crimped the wires from the radio harness to the adapter and it was plug and play. Didn't cut a wire.

Once you get that harness its amazing how easy the install is. Vdub harness I would have never thought of on my own seems like deere would have picked the gm and ford a domestic harness but I guess a harness is a harness in the end.
