Some of you have had problems using the CUI phono jack (sound only comes out of both speakers when you have the plug pulled out a bit). I am about to wire up my own fit using the CUI jack and I know what your problem is...

The original instructions for this jack list the following:

Use Diagram B and connect the following:
3.5mm Jack to Harness
Terminal 1 to B15 (AUX DET)
Terminal 2 to B14 (AUX R)
Terminal 3 to B13 (AUX L)
Terminal 4 to both B3 (AUX SIG GND) and B4 (AUX SHIELD GND)

However, this is incorrect based on the CUI schematic. Here are the correct wiring instructions:

Use Diagram B and connect the following:
3.5mm Jack to Harness
Terminal 1 to B13 (AUX L)
Terminal 2 to B14 (AUX R)
Terminal 3 to B3 (AUX SIG GND)
Terminal 4 to B4 (AUX SHIELD GND)

B15 (AUX DET) just needs to be "jumped" to any of the ground signals. In the OEM jack, there is a switch that connects AUX DET to ground when a plug is inserted. But, there is no switch on the CUI jack, so this should be permantly connected to ground. This will solve the problem that most of you are having with the CUI jack. This does NOT apply to the Radio shack jack. The terminal numbers are not related to the ones on the CUI jack.

Thank you to everyone that has risked their car and shared their experiences. It made the process much easier for the rest of us. I'll let you know how my installation goes...Wish me luck!
