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 ***Direct to ground *Intake Air Temperature Sensor **Grayblue ***Pin 2 on EC36 **Green ***Direct to ground *Throttle Position Sensor **Yellow for +5v ***Pin 28 on EC36 **Pink for ECU input ***Pin 1 on EC36 **Green ***Direct to 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 ***Direct to 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). ***''Response to Marcell: Yes you are exactly right. Pin 3 (see diagram below of G28 which is crank sensor) shows no continuity between the other two pins. Pins 1 and 2 show about 554 ohms. And this means...?'' *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 EC18 *Knock Sensor **Blue for ECU signal ***Pin3 on EC18 **Green for ground EC18 pin 2 **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 **MembersPage/PhatBob/UserGuide has a layout of the wbO2 plug *Misc ECU Grounds **Green ***Pins 5, 21, 32 on EC36, pin 2 EC18??- the diagram shows these to tie into the sensor grounds. I think I'll just leave them as individual wires and ground them at the same places. '''Diagram of crank speed sensor (G28)''' ''Oh what does the dotted line loop around the wires from pins 1 and 2 that has the line from pin 3 mean?'' http://www.starshadow.com/~koabi/carstuff/VEMS/060418g60ISVandknocksensor.JPG Optional: Add document to category: Wiki formatting: * is Bullet list ** Bullet list subentry ...
