Im currently wiring a AEM Fuel/Ignition Controller because im fed up with the SAFC's lack of tuning capability at low boost(cant turn down the injectors). The wiring diagram has specific wires that attach to the VR crank sensor wires and it asks for the postive and negative crank wires but my mercedes diagram marks them differently. The car does have a VR crank sensor but its marked "high side" and "low side" wires. Am I to assume the "high side" is the positive wire and the "low side" is the negative?


EDIT:
Only one cam sensor right?
