Yes, if you are still with me, the 6pins are free. I want to use the EC36-34 ch2 to run a 2.nd fuelpump. I believe this is connected to one out of 2 possible channels on this extra pin.
Why do you want to use spare ecu output to switch second fuelpump? why not connect it parallel with the first one?
Re the wheelspeed. Its coming in there, but there is nowhere i can choose the correct pin for it in vemstune.
V3.3 does not have wheelspeed input connected to motronic connection.
This is the most used extra pinout on motronic:
AAN ECU extra connector pins:
SSC6 feemale
pin1 mcp3208 pin6,ch5
pin2 mcp3208 pin7,ch6
pin3 mcp3208 pin8,ch7
pin4 EC36 pin 34 (power out)
pin5 EC36 pin 36 (power out)
pin6 GND
Pin 1 does not have internal 5V pullup.
2 and 3 have 5V pullup and grounding them from pin 6, you can switch stuff.
Pin 4 and 5 are power outputs and are grounded when active.
