CONNECTOR AND WIRING DETAILS
3.4.1
MAIN HARNESS 12 PIN CONNECTOR
3.4.1a
Red (+) Constant Power Input
This wire supplies the main power for the MFC and must be fused. Before
connecting make sure P2-Black is wired to a solid chassis ground.
3.4.1b
Black (-) Chassis Ground
Connect this wire to a paint free metal chassis ground. Make sure wire has a
solid connection and does not move around
3.4.1c
Green/Yellow/Pink/Orange ACC1-4 (+) or (-) Outputs
These connectors are output from the 4 MFC internal relays (rated up to 12v
@ 30amps peak). These wires will be connected to the vehicle accessories
such as door locks, radio turn on, trunk release, etc... They can all either
send a (+) or (-) Signal depending on what the ACC source input wire is
connected to. (P8-white wire) See pg10 for details.
3.4.1d
Brown -Tachometer Input
With this wire connected to the vehicles tachometer signal wire, it will allow
you to get an RPM read out on the Connect2Car SOFTDASH Software running
on your controller device (e.g. phone, PC or PDA, etc). The RPM can be used
in REMOTE START recipes to synchronize with the RPM while starting (as well
as using a limited pulse time). It can also be set up to activate any specific
output based on the RPM (e.g. activate/deactivate an output below or above
a desired RPM level). For accurate performance of the tachometer readings,
the tachometer must be calibrated from the SOFTDASH software interface.
3.4.1e
White (+) or (-) ACC 1-4 Source Input
This is the input for the internal relays that control P3, P4, P5, and P6. If
connected to a 12V+ the outputs of Acc (1-4) will then be 12V+. If connected
to a (-) chassis ground the outputs will then be (-). This wire must be fused
with a 30A max fuse to protect the vehicle and MFC board in case of a short.
