'09 5-Door LB - Aux Jack Harness is different.

[IsLNdbOi]

Got it done last night. Went ahead and just used T-Taps w/ quick slide connectors. I didn't have to buy a new cable to do this either. I had leftovers from this cable:



When I did this aux. jack modification on my '07 LB, I cut the above cable in half and used the end with the RCA connectors for this modification and kept the other end (the one with the 3.5mm connector) in my spare parts box.

Worked out perfectly because my new HU has a 3.5mm input on the back. All I had to do was crimp male quick slide connectors on each of the four wires. After the connectors were crimped on, I simply slid each one into the T-Taps I put on each wire on the stock aux jack's harness.

Connections:

- red wire from 3.5mm cable to ARI
- white wire from 3.5mm cable to ALI
- one of the black wires from the 3.5mm cable to ASGN
- the other black wire from the 3.5mm cable to AGND


This cable I used has four wires matching the four wires of the new aux jack harness:



I tested the wires first before crimping and connecting. The sound didn't change at all when I switched the cable's two black ground wires around (connecting each to the ground shield and audio ground on the aux jack harness).

what wires on your stock aux harness did you use though?

Sorry to thread necro, but is this the reason why i get humming sound only when on IGN and not on ACC? I left the AGND out as i was under the impression only pins 15, 16 & 17 were involved in the audio transfer-so pin 18 AGND wasnt connected to anything.
