Thread: how-to: diy aux input for 04+ xm equipped cars

idk what im doing wrong but I tried hooking it up and the first time the xm channel was stil going when i had my music playing. I was using the orange as negative(to audio common), and one of each red to left and right. what am i doing wrong? I took wire # 2, 3, and 10 from the connector. at one point when i was trying different wires the xm channel cut out and there was weird bass.

any help is appreciated thanks.


Brown: AUdio common
Black: Left audio
Strippedwire: Right audio


Red: Presumed Positive
Orange/yellow: Presumed Negative

And also the three wires you cut should never ever be hooked together 2 are posited and one is a ground. Looks like you have audio ccommon(-) to audio right (+).

all i did was cut off rca's. so the 3 wires that I cut don't get hooked back together? they just attach to the new cable into the harness then plug in? in the picture my audio common is connected to audio common bc i thought i had to connect the wire itself back after cutting it in order to attach to the rca wire.
