MK1 VR6 OBD2 Plug and Play Engine Harness
Before connecting harness please ensure you have an adequate motor-to-battery
ground by cranking motor using starter. If it cranks slow, check battery
condition and battery-to-motor connection. If the ground is not adequate the
starter WILL GROUND THOUGH HARNESS melting harness and will not be a warranty
condition.
Hook the two battery leads labeled “battery” to battery positive post, and be
sure to use a 12 gauge inline fuse at battery-30 AMP fuse in each.
Extend lead labeled “fuel pump” to fuel pump(s) positive posts. Disconnect any
other leads at fuel pump positive posts and tape up/tie out of way. Be sure
pump stil l has a quality ground. *NOTE: Cabby’s have a lift pump and external
pump so be sure to get both powered up. Use only quality 12 gauge wire to
extend lead.
Ground leads labeled “body ground” to a clean bare metal surface at/around
ECU- a self-tapping screw into tin is fine as long as it tightens well….a nut
and bolt is preferred.
Lastly, hook wire labeled “trigger lead” to ANY lead that goes 12V hot when
key is in running position AND in CRANK POSITION, if this cannot be found then
a simple toggle switch from battery power can be used as a “master” switch for
on/off of engine.
Last two wires in T42 connector are oil pressure and temp gauge- none need to
be hooked up but can be wired into stock harness for proper cluster operation.
For a tachometer signal please google “VR6 TACH lead” as it requires tapping
into coil pack itself and using resistors for proper signal.
