Thanks again!
I thought the speedometer sent the signal to Pin 34 of the ECU, so I can just bypass the speedometer, and send the signal directly to pin 34. Do I just apply 12V to one wire of the speed sensor, and the other would be the signal wire to Pin34?

The speedometer contains a circut which converts the sine-wave from the diff sensor into a square wave for the ecu's. The output is an open transistor emittor, and pulls the ecu-input low. It can not be replaced with just a cable from an ABS sensor. When installing a 960 driveline in a 242, I removed the circut board form the speedometer (not to be confused with the instrument cluster), and used this to get signals for the ecu's and 240 speedometer
