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 plug layout *Wasted Spark Coil **Red for +12v **dark gray coil driver 00 ***Pin 35 on EC36 **light gray coil driver 01 ***Pin 33 on EC36 **ground (if pin 4 is really a ground) so need to find plug layout *Crank Position Sensor **Purple ***Pin 27 on EC36 **Green ***To analog ground **Another Green (shield) ***Also to analog ground **This sensor has 3 pins. On the ABA jetta diagram *** one goes to ground (resistance to other 2 pins > 2 MOhm, right ? if so, this is shield GND) *** two go to the ECU. Resistance between the latter two is .... Ohm in both directions (I expect something like 450..900 Ohm). *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 3 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 *ECU **Red for +12v ***Pin 25 on EC36 **Black for ground ***Pin 26 on EC36 - this goes to analog ground EC18 *Knock Sensor **Blue for ECU signal ***Pin3 on EC18 **Green ***EC18 pin 2 for ground for both signal ground and shield ground **I think pin 1 on knock plug goes to the ECU and 2 and 3 are both ground *WBo2 **Red for +12v **Yellow, blue, black, white for rest - pins 7,9,13,18 on EC18 WBo2 plug *MembersPage/PhatBob/UserGuide has a layout of the wbO2 plug **Yellow, blue, black, white, red (for +12v) VR crank sensor plug. Note that HALL sensor needs + supply (usually 5V) so it cannot be HALL (=> it is VR) if it has no supply. *purple to ECU *http://www.80tq.com/~wiz/gallery2/d/35-2/Sensor+-+VR.png Knock Sensor plug *Pin 1 - Blue to EC18 pin 3 *Pin 2 - Green to EC18 pin 2 *pin 3 - Green to EC18 pin 2 as well 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 *Black **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) Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
