Electrical Connections – For the Signal and Ground wires:
- Systems using a three (3) wire Hall Effect Device (HED) crank sensor, use header connector 2, pin W1 for
the signal wire and W3 for the sensor ground wire.
- For traditional IPU applications and the Ford Mod motor system, use header connector 1, pin E3 for the
signal wire and J2 for the sensor ground wire.
Swagelok 6AN fittings are
recommended to connect the
return lines to the sensor in
and out tubes. One (1)
reducer and two (2) unions
are needed.
- Reducer P/N: SS-500-R-6
- Union P/N: SS-600-6-6AN
