Got mine done this weekend. Came out great. Thanks for all the contributors on this forum. I don't have USB functionality on the front 3. I did Bilsteins, Console swap, and Katzkins. It was a lot to take on in one sitting. I thought it would be easier to knock out the Katzkins and center console together. Looking back, it was enough work that I probably should have done the jobs separately. The console swap isn't bad, but combined with Bilsteins (3 hours) and Katzkins (12 hours), it was overwhelming.
As far as the console swap by itself, I followed the directions in this thread and had very little trouble. The wiring is easy, but you have to think, plan, make sure everything will fit, etc....Make sure you have a good soldering iron, shrink wrap, and wire strippers for 20 Gauge wire. Someone could write down a super detailed description about wire colors and exactly what to do, but it's mostly intuitive.
Basically completely remove all the tape and salvage the USB cable from the jump seat. Unplug the console USB and let in hang in place. Plug in jump seat USB in its place. This will plug in to the harness under the seat as it did before.
Cut 12-14 inches off the jump seat harness. Solder all similar colors. There will be two extra (purple and yellow 14 gauge I think) on the jump seat harness side and one on the console side for the light (20 gauge blue and red). Tape up the purple and yellow. They will not be used.
Salvage one cigarette lighter harness from the jump seat and cut with 8 inches of wire. Cut the ashtray cig plug where you have enough room to solder/splice it. Solder the additional cig lighter harness to the existing one along with the 20 gauge light wire. I think I had to extend the light wire with some salvage wire as well. Now, where there was originally one cig plug with full time power, you will now have 2 cig plugs and the console light in a three way splice.
This gets everything but the front USB's working. I ran out of parts, brain power, and patience to attempt this.
So inverter is plug and play. USB under lid is plug and play. Rear cig, under lid cig, audio are fixed with the soldering of the harness. Additional front cig and light are spliced into existing cig.
