Completed the harness for the Bauman/4R70W. I ended up using the bulkhead connector off the 4.6 2V GT harness I had that came with my 4R70w.

The backup light wire/pin on my ECU harness to the trans matched the GT 4r70w hareness (black with pink stripe), but the power feed to the trans did not match (solid orange on mine, purple wire with orange stripe and also in a different pin location on auto GT harness)

I pulled apart the bulkhead connector and moved the wire on the GT harness to the correct pin location so it matched my ECU harness. I then removed all other wires from the bulkhead connector (O/2 sensors, trans sensors, etc..these are already in the bauman harness)

Left over GT harness

Here is a picture of the harness completed laying on the ground. 

The harness branches off to the neutral safety switch/circuit (which i will tie into where the clutch pedal was), Throttle Position Sensor (which i will tie into at the bulkhead connector by the firewall), Solenoid Ground (chasis ground, seperate from power ground), main power/main ground, and finally converter/overdrive/table switches (which i will wire up when the interior is installed.

This is the segment exclusively for the transmission. You can see the longest harness is that which will connect to the ECU harness/made/described earlier.

This segment is for the various connections inside the car/engine bay

Here is a picture of the fuel distribution block I made and partially installed. I'm hiding this inside the pass. inner fender along with the hobbs switches/guages/sensors to keep the clutter out of the engine bay. I will do the same thing for the oil system.

The last picture for tonight is the power distribution block and wire feeds for the various guages that will be mounted on the A Pillar.

So here is the shifter assembled....it's not going to install, plain and simple. Not without taking the cap off, or cutting away metal...

So, I disassembled the shifter and tried again. viola! Installing it from the bottom disassembled allows you to actually take the lips on the shifter and tuck them into the edges of the trans tunnel (this is where it mounts to on an automatic)...here it is on a 'test fit'

next I installed the center console and shifter trim bezel to get everything lined up. It's pretty amazing that it needed VERY little adjustment...

I marked the shifter body with paint to note where i would have to drill holes so it could be mounted to the cap. I then milled out the existing holes (the paint marks were right next to them) and mounted the shifter into place.

Next was installing the Bauman harness that I made yesterday. I didnt want to drill a giant hole in the floorboard or trans tunnel to feed the large bulkhead connectors through so i removed the shifter and ran the harness through the shifter hole. I then reinstalled the shifter and clearanced it so it was just tight enough but not too tight to where it might wear through...I snaked the harness around peaks and valleys and installed the center console, again, to make sure everything fit. 

Time to get some sleep! The carpet will go in tomorrow along with the final connections/soldering for the bauman. The engine comes in tonight so some serious progress is about the happen!
