Doesn't work

I have a 2002 Audi TT with Bose Concert II system, this harness was supposed to enable me to install my new Pioneer aftermarket HU. The harness requires you to have two preamp outs on the HU, and also will not work if you hook up switched power wires together, or the dimmer wires. You need to run custom wires for your dimmer and switched power. The rest of it worked, but why wasn't there instructions on how to properly hook it up?

Not Bad!

All adapters match up perfectly! Wish they left a little more of the wires stripped, but it worked out ok. Highly recommend.

Make sure that you are getting the correct harness.

My Audi has a Symphony system and this harness only works for the Bose.
