Drives to GND, and is limited to 400V and 10Amps. 40V-OD = Open drain. Drives to GND, and is limited to 40V. 2 or 10Amps. 1k-PU = 1kOhm pull-up resistor. Used with Hall element or switch to GND. 1M-PD = 1MOhm pull-down resistor. Used with 12V input signals. 22k-AC = 22kOhm AC load. Used with Inductive crank/cam sensors. 60k-AC = 60kOhm AC load. Used with ex. Inductive ABS sensors. Ignition FET's IRFP450 cannot be mounted if 5V-PP ignition outputs is to be used. This is the case when external ignition modules are used. J201 : 1k Pullup to 60-2. Mounted: Hall. Not mounted: Inductive. J202 : 1k pullup tp Intake Cam. Mounted: Hall. Not mounted: Inductive. EGAS Configuration: --------------------- J304 mounted: H-bridge output on pin 4. J306 mounted: H-bridge output on pin 22. Pin 52 = Potmeter is the potmeter in the cabin of the car. Pin 43 = Egas feedback is the potmeter on the trottle body. Not EGAS: ----------- J304 not mounted: Pin 4 is driving low only. J306 not mounted: Pin 22 is driving low only. Pin 52 = Potmeter on the trottle body. Pin 43 = Can be used as 0-5V output, temp measurement (R243=4k7) or other. Using Wideband sensor: ----------------------- Check if 56 Ohm mounted between pin 10 and 12 to get 2.5V on LambdaGND. Check if Pin 28 connected to pin 53 to measure sonde impedance. Wideband sensor Bosch 0 258 007 057. Harness Connector for wideband sensor: VW 1J0 973 733 Using Lambda sensor: ----------------------- 56 Ohm not mounted between pin 10 and 12 to reduce power consumption of ECU.
