---- '''Navigation''' * Main MembersPage/KoabiBrooks * Ignition MembersPage/KoabiBrooks/Ignition * Injection MembersPage/KoabiBrooks/Injection * Wiring MembersPage/KoabiBrooks/Wiring * Q&A MembersPage/KoabiBrooks/Questions ---- '''WIRING PAGE''' http://www.starshadow.com/~koabi/carstuff/VEMS/060407everything.JPG Current wiring notes (note, connector names from bentley manual): *T2f (black connector by master cyl) R/Y should be fed to VEMS FP output **PIN 15 on EC36 *T2f (black connector by master cyl) R/W should be fed to O2 sensor heater AND fuel injector power supply **pin 3 on LS4U is heater supply **Is running injection supply off of this source also going to be too much? ***Who knows! add 10a inline fuse if this ends up being supply for o2 and injection *T3d (white connector by master cyl) black should feed VEMS +12v **Pin 25 on EC36 ---- http://www.starshadow.com/~koabi/carstuff/VEMS/060409wirestomainharnessfar.JPG Note: coolant bottle is removed for viewing. http://www.starshadow.com/~koabi/carstuff/VEMS/060409wirestomainharness.JPG Close up *The top connector is a 2 pin mystery connector. **Green and violet/black on the engine harness side (left). **Green and blue on the main harness side (right). **Green was for #50 starter trigger. 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. GrmRacer, can you tell me what gauge wire you sent me? there are two gauges. I want to make sure I use what's appropriate. WIRES and GAUGE *WBo2 - thicker gauge **Red for +12v **Yellow, blue, black, white for rest **Need to find plug layout... *Coolant Temperature Sensor - thinner gauge **Orange **Ground *Intake Air Temperature Sensor - thinner gauge **Grayblue **Ground *Throttle Position Sensor - thinner gauge **Yellow for +5v **Pink for ECU input **Ground **Need to find plug layout *Wasted Spark Coil **Red for +12v - thicker gauge **light green for one pair (thinner gauge ok?) **dark green for other pair (thinner gauge ok?) **ground (if pin 4 is really a ground) so need to find plug layout *Crank Position Sensor - thinner gauge **Purple **Ground *Fast Idle **Red for +12v - thicker gauge **Beige to ECU - thinner gauge? **VW ISV have 3 pins. gotta figure that out. *Fuel injectors - thicker gauge **Red for +12v through flyback **yellow, blue,white, black for ECU triggers
