so i have a pioneer f900bt and i was trying to install it yesterday but i only got 2 wiring harness pieces so i still have two empty plugs left and i dont know what to do. do they sell those or do i have to cut them and crimp them together? i think the only one i got was for the power. i think i need ones for the speakers and amp?

 

there should be one for power and rear speakers I believe and one for the front speakers and amp turn on/antenna wire. you only need the two

 

ok so what do i do with the extra plugs coming from the car?

 

One plug is for the steering wheel control - you need this one to connect the PAC-JACK steering wheel controller. The other plug is the factory sat prewire - you don't need it.

 

ok thanks. one more question. the two harnesses i have one has a blue wire, a black wire and one set of RCA cables. the other has the Power ACC Ground Illumination a Blue wire and a set of RCA cables. does that sound right? the two harnesses here>http://www.scosche.com/products/productID/623

dont have RCA cables on them. do i have the wrong kit?

 

It sounds like you have the right kit with the RCA plugs. You them into the RCAs coming out of your radio.

 

ok ill try that then. thank you guys for the help.
