Parts used:

SCOSCHE NN04RB Reverse Stereo Harness
SCOSCHE NN04B Stereo Harness
Speaker Wire

Pinout:



1. Since the harness has more connections than needed and missing in 2G in the pinout above. We have to remove and rearrange some of the pins. Used a bobby pin that had been dremel down in both width and height.

How to remove wires. Just push into the flat slot and pull the wire out the back.



Removed the Orange, Orange/White and Blue wire from the new harnesses. Added the blue wire back to the slot under the red wire.

How both harnesses should look afterwards.



2. Solder all the wires together and add some speaker wires in between matching speaker wires. Add a extra wire to the ACC if you want a amp turn on. You will end up with something like this:



Wrapped upped in Tesa tape:



Ended up with 3.2V coming out of the wires which you can leave as is or solder RCAs on.

Why did you use an LOC? Did you measure the voltage coming from the wiring?
Just what I had on hand and I plan to use the unamped side on the other end to run some 3.5" speakers to the dash. I did not test the voltage at the wiring but speaker wire colors are above if anyone wants to test.

Sigh... you need to measure the voltage coming from what you think is the amplified side before using an LOC or you may reduce the signal too far.
Thanks for the suggestion. Measured 3.2V coming out of the TAU. Removed the Line out converter and soldered on RCAs. 20% gain on the amp will get my Infinity speakers super loud now. Will update the thread later since it would not allow it for 10 days.

Does that tee harness plug into the Bose plugs or TAU plugs? I wouldnt mind using a plug to plug connection when i do mine. And that 3.2V will pair nicely with my Kicker ZR and ZX amps :)

Straight into the TAU if you have the newer 20 pin style connector on the top port. As long as you get the regular and the reverse stereo plugs and repin that one missing pin.
