Digifant needed it, VEMS doesn't. *The middle connector is T3d per the Bentley manual in the 16v engine section. **black on engine harness side and engine harness side ***Switched +12v ***Two wires from one pin, one wire from another pin on engine side (left) ***One loopback on main harness side (right) to power additional pin **Red/black on engine harness side and main harness side ***This is off the starter relay...it's only powered when the starter is cranking... *The bottom 2 pin connector is T2f (the black connector) **Red/yellow on both sidse ***From fuel pump relay output - route to ECU to allow priming. **Red/White ***+12v switched that originally powered O2...will be used for that again. ---- '''VEMS Harness''' Here I will try to describe the harness I am creating. WIRES - Greens are ground EC36 *Coolant Temperature Sensor **Orange ***Pin 14 on EC36 **Green ***To analog ground *Intake Air Temperature Sensor **Grayblue ***Pin 2 on EC36 **Green ***To analog ground *Throttle Position Sensor **Yellow for +5v ***Pin 28 on EC36 **Pink for ECU input ***Pin 1 on EC36 **Green ***To analog ground **Need to find sensor plug layout *Wasted Spark Coil **Red for +12v **Dark gray coil driver 00 '''NOW COIL DRIVER 03?''' ***Pin 35 on EC36 '''NOW PIN 36 ON EC36''' **Light gray coil driver 01 '''NOW COIL DRIVER 05?''' ***Pin 33 on EC36 '''NOW PIN 12 ON EC36''' **Green ***Straight to power ground **Need to find sensor plug layout *VR Crank Position Sensor - 2 wire shielded cable **White (Note to self: was going to be purple) ***Pin 27 on EC36 **Black ***To analog ground **Shield ***Also to analog ground **See trigger page for sensor plug layout *Fast Idle **Red for +12v **Beige to ECU ***Pin 3 on EC36 **VW ISV have 3 pins. Looks like the Corrado G60 ISV only uses 2 pins. ISV connector pin 3 for power, pin 1 to ECU. *Fuel injectors **Red for +12v all the way through flyback ***Pin 23 on EC36 **Black - injector driver A ***Pin 7 on EC36 **Blue - injector driver B ***Pin 19 on EC36 **White - injector driver C ***Pin 8 on EC36 **Yellow - injector driver D ***Pin 20 on EC36 **Will Probably use 3 2pin JPT connectors: 1 connector for 12v supply and flyback, 1 for one pair of injectors to ECU, 1 for the other pair of injectors to ECU *Fuel Pump Relay Trigger **White ***Pin 15 on EC36 *ECU **Red for +12v ***Pin 25 on EC36 **Green for ground ***Pin 26 on EC36 - this goes to analog ground *Spare wires **Purple **White? **Blue? **Yellow? EC18 *Knock Sensor - 2 wire shielded cable **White for ECU signal (Note to self: was blue) ***Pin 3 on EC18 **Black ***Pin 2 EC18 **Shield ***Pin 2 on EC18 also **Pin 1 on knock sensor plug goes to the ECU and 2 and 3 are both ground (grounded through ECU in this case) *WBo2 **Red for +12v **Yellow, blue, black, white for rest - pins 7,9,13,18 on EC18 ***Exact usage to be determined **Sensor plug layout: MembersPage/PhatBob/UserGuide Misc ECU Grounds *Green **Pins 5, 21, 22, 32 on EC36. These are the "power" grounds and go to the main ground point **Coilpack will go to the main ground point *Green **Pin 25 is the analog ground. There will be some ground distro near the ECU that all the sensors will go to. '''NOTE: This distro IS NOT to be connected to the car ground besides the single wire that connects it to the main ground.''' **CLT, IAT, TPS, VR, will go to this ground distro. For VR and both signal ground and shield ground will go to this analog ground. For KS, both signal ground and shield ground will go to EC 18 pin 2 (see KS section above) *Black **Ground from the sensor ground distro to power ground point Missing! * Boost Controller solenoid output ** a free output on EC36 (or EC18: the stepper output also fine unless all 4 used for stepper). GenBoard/Manual/DigitalOut/Table *Fuel Pressure ** an mcp3208 analog input on EC18, (pin12, 6, 16) depending on [http://shop.vems.hu/catalog/product_info.php?cPath=1&products_id=48 assembled options] *WHAT ELSE SHOULD I LEAVE WIRE FOR (think future upgrades) ** delayed self destruct button ;-) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
