I ended up picking up one of these:
https://www.ebay.com/itm/334207074538?h ... SwRLxeXwsl
and used it to build an adapter that I'm using for now with a Zombieverter VCU.
I ended up actually using the connector for 3 from the transmission to pickup the shift up/down as momentary buttons to select direction. I also had to move the reverse lights relay wire to an empty pin on one of the other connectors since it was the only other pin on the transmission connector I needed.
If anyone wants to do the same here is the rough pinout:
X60001:
Pin 4: Ground
Pin 7: T30 Always on 12V
Pin 8: T87 12V turned on by the DME Relay (using for various accesories)
X60002:
Pin 8: Moved reverse lights relay from X70004-40
Pin 23: DME Relay
X70003:
Pin 1: Ground for shifter lock
Pin 2: Signal for shifter lock
Pig 19: Tip up (Reverse for me) (had to add a bit of circuit on some of the unused pins to convert the low side signal to a high signal for the VCU)
Pin 20: Tip down (Forward)
X60004:
Pin 3: SAP relay (using for oil pump)
Pin 4: Fan
Pin 7: Ground Pedal Value Sensor
Pin 8: Signal Pedal Value Sensor 1
Pin 9: Supply Voltage 1 Pedal Value Sensor
Pin 12: Ground Pedal Value Sensor
Pin 13: Signal Pedal Value Sensor 2
Pin 14: Supply Voltage 2 Pedal Value Sensor
Pin 24: Brake light
Pin 26: T15 vehicle on 12V
Pin 27: Steering wheel LIN (for cruise control some day)
Pin 29: AC Relay
Pin 33: EWS signal (I shorted this to the T50 from the ignition switch at the EWS module to get a nice momentary start signal)
Pin 36: Can High
Pin 37: Can Low
X6005: Unused
I actually do have a design to build a somewhat simplified version of the Zombieverter in as MS43 form factor using a Olimex STM32 F107 header board that I could share, but it hasn't been tested at all.
Once I have all of the features implemented in my car I may go back and revive this and try to merge the VCU and the adapter into a single box. There are plenty of pins left to implement things.
