Gearbox Controller 722.6 ver 2
(01-31-2015, 01:00 AM)TurboTim I have the top picture. I have the "speedo ext" wire to pin 5, its a white wire and I also have the 2 other, power and ground. I tried setting to -3 and 1 and still am not getting anything. Could there be some other setting in the software I could have messed with or need to? Is it possible the output got damaged. I did have it hooked up to a green with white wire that goes to the cruise module that I thought was the speedo input but I think its actually the speedo input from the cluster? The wire has 4 volts KOEO. Is the circuit protected because it seems even when I scope it I get nothing.Just connected it this morning on the Table
So I just looked at your manual again and I am very confused about what pin to use. You have a pin for "EXT Speedo" but in the manual it says use pin D47 as far as I can tell, but then my Tacho output is on D37?
Last update of the night....so D37 should get wired to the white wire on pin 5 behind the cluster. I still have to mess with the number but I am pretty sure 15 will be too low of a number for me. I will update tomorrow for people who are putting this amazing controller into a 300SDL in case the wiring is different for other cars.
