Power Grounds
Also called as "GND5" in some documents
• EC36-pin5 to Common Ground
• EC36-pin21 to Common Ground
• EC36-pin32 to Common Ground
• EC36-pin22 to Common Ground
Sensor Ground
• EC36-pin26 to Common Ground. NOTE: Sensor Ground pin has many connections (CAS, TPS, IAT,
CLT ...) make provision for this in your wiring loom.
+12V Supply
• EC36-pin25 3A Fused +12v supply
Note that if you have moved the battery to the rear of the car you may want to run separate wires for
the starter/alternator and for the cars electrical system to the battery. Otherwise the several meters long
cable will cause a significant voltage drop during cranking that will cause the ECU to reset when the
battery starts to run low. This may prevent the car from starting even if the engine cranks over.
Once you have connected and checked the continuity of ground you can connect your VEMS
unit to the EC36 plug and apply the power supply. There is little point in connecting power until
the serial connector is added though.
