Axxess ASWC-1 Steering Wheel Control Adapter

I have a 2005 base Prius and need help with the wiring of an aftermarket Radio . The directions for the ASWC-1 say the oem plug is a 20 pin but I`m having a hard time knowing which wires go where .

 

had my neighbor hook it up the only thing not working is the steering controls

 

Okay so the steering wheel controller was not that difficult after all but for me it was The red and black wires are easy enough they can tap in with the new stereo red and black wires . Now the more involving part was the radio has a 20 pin harness that isn`t used with the aftermarket stereo . But instead you use 3 of the wires to connect as shown in the pdf . Also the metra kit 95-8240B comes with the resistor to connect the 2 wires at pin 9 and 10 to stop problems with the climate control . I ended up installing a Kenwood DPX500BT just $150 on amazon So to clarify you only use 5 wires from the big bundle on the Axxess ASWC-1 , the black ,red ,green orange which looks like green tan to me ,black green and then the brown wire goes to your aftermarket stereo if you have a kenwood .
