miker1017 Posted April 23 Report Share Posted April 23 I was wondering can I use the 8v a6 pin to power a m54 hall effect cam sensor, or should I use switched 12v? Also can someone please guide me on the sensor pinout? I seen a pinout sheet on another forums it showed + , U, - What does the U mean?

curly Posted April 24 Report Share Posted April 24 It might work on 8v, but the OE harness uses 12v shared with cam, crank, and maf sensors, among others. Pin 1 is 12v, pin 2 is signal, pin 3 is sensor ground. BTW I swapped a E36 from S50 to M54 (easier to find uncracked heads), and the exhaust VANOS is near useless. Use the intake VANOS and feel free to leave the exhaust unplugged/unsensored. Confirmed this with Randy at EPIC Motorsports. Might help with emissions, but in terms of power, don't bother.
