brake gas throttle cutout thing 88 5000 T Q

[Bernard Littau]

Hi Ken,

Pin 6 is the wire used by automatic transmission cars.
See:
http://www.sjmautotechnik.com/pinout.html#ten

As far as I know, the ECU's are identical between manual and auto cars (and
CA cars).  The wiring loom to the connector on the ECU is where mine has the
CA wire cut, for instance.

Good luck figuring it out!
