Ok, So I am trying to install the Pioneer ACIV-X920BT on my G35. I have the JDM double din harness, metra 70-7551 harness, and Axxess steerign wheel controls. This is how i have my wiring done:

Legend
(M) - Metra Harness
(P) - Pioneer
(A) - Axxess

-R(M), R(P), R(A)
-Y(M), Y(P)
-O(M), O/W(P)
-BU/W(M), BU(H), BU/W(P)
-BK/W(M), BK(H), BK(P), G(P), Y/BK(P), BK(A) bypass
-RCA GRAY(M), LEFT FRONT(P)
-RCA WHITE(M), RIGHT FRONT(P)
-RCA GREEN(M), LEFT REAR(P)
-RCA VIOLET(M), RIGHT REAR(P)

Now for the steering wheel Axxess Control it says to connect the Gray/Red wire to pin 4 of the car, the white/green wire to pin 13 of the car, and to connect pin 11 of the vehicle harness to the ground. Would i have to cut these wire from the harness or is there a way to keep the harness?

Any suggestions on the wiring?

 

This is in the wrong section....
