Until I find and install a factory amplifier, I created leads to interconnect the speaker outputs of the radio to some of the factory speakers.

Not all 4 channels route through the factory wiring loom to the amplifier. The factory radio sends a left and right channel to the amp, and then bus communication messages handle the fader, balance, etc. right from the amplifier.

At least the factory connector and wiring is left in tact, this way

Here is the radio back in the dash (sorry for the dark picture). At least I can sleep better knowing what the real situation is with the wiring behind it, now!  I do still have to sort out why the ASWC-1 is not powering up, though, so that I can get the factory steering wheel controls working.

I also re-located the handsfree microphone. This position puts it closer to the driver and hides the wiring better, as the original location had it clipped to the headliner trim right against the windshield.

Here is the dash, ready for the correct adapter to be attached and the have the radio reinstalled.

I also used the Metra 99-9302 mounting adapter plate, which was left out of the previous installation work. The Pioneer radio sit more firmly in the dash, now.

There were a couple of wires to clean up at the radio connector, too.

I keep some soft-wrap tape on hand for repairs like this...it matches the style used on the factory wiring loom.

After a lot of solder and heatshrink, all the factory amplifier wiring connections were restored.

After all the unnecessary boxes were removed (there is a simpler Pioneer headunit in the car now that doesn't use all those extra modules), here is what I found for the BBY amplifier by-pass work.

At least the factory amplifier connector was still there, but the speaker wiring connections were all hacked up as they tried to make some sort of connection from the radio to the speakers while by-passing the factory amplifier connection.

The factory HK amp sits underneath the passenger seat...or at least, it should.

The previous owner mentioned that Best Buy did the aftermarket radio installation...and it shows. The first aftermarket radio that was installed was a single-DIN fli-up Pioneer AVIC unit - which is a really nice radio, but requires a lot of additional boxes. I've seen/fixed a number of BBY installations, and my read of their work is that their main concern is finishing the install quickly (time = money, right). In t

Here's another view of all the wiring that was in the dash just for the aftermarket radio. Way too much extra length left on the wires. On the plus side, they didn't just cut off the factory radio connector, and they used an adapter...but this car needs an intelligent adapter to work with the factory Harman Kardon amp and speakers, and they didn't use that.

So, I take the dash apart, remove the radio and find...this.

Wiring nuts do not belong on a vehicle accessory installation. And there is no sign of the proper interface to connect to the factory Harman Kardon amplifier.

This is the wiring adapter for the AX-BM9112 
adapter to be used with the factory Harman Kardon amplifier.  It's all wired up to the Pioneer's radio connector harness.

Only about 3mL or oil drained out of the waterpump side of the supercharger.  I refilled it with 40mL of fresh AC Delco supercharger oil 10-4041 or 12345982 .

The color of the oil drained from the waterpump side of the supercharger wasn't too bad...there just wasn't much of it left after almost 160k miles.

This is the oil as drained from the pulley side of the supercharger.  It looks darker as gathered in the container, but as it drained out of the supercharger it actually didn't look as dark as I feared it would.

Altogether, about 70mL drained from the pulley side of the supercharger.  I refilled it with 140mL of fresh AC Delco supercharger oil 10-4041 or 12345982 .

The coupe's console is longer than the cabrio's, so I lined them up and marked the coupe console for trimming.

I've included the details of the changes needed to the coupe center console: adding a hole for the trim screw that's at the front storage tray, cutting off the tabs at the front, and trimming off the extra length at the back.

Here is a side-by-side of the consoles after the coupe console had been trimmed to match.  The angle of the picture makes them look like they are different lengths, but they are the same.

Another item I tackled was reattaching the BSR felt on the side of the seatbelt latches (they had curled up at the edges).  
I have some very thin 3M VHB (Very High Bond) PSA (Pressure Sensitive Adhesive) that I applied to the felt and it will insure that they stay in place going forward.
