Connecting The MPC02 Power Harness...

RED (Power) and BLACK (Ground)

1.

Fold the floor covering so that access is gained to the factory wire harness routed under the driver’s seat
area.

2.

Insert  the  Power  Input  Harness  into  it’s  port  as  shown  in  Fig.  1.  Be  sure  that  the  RED  wire  is  located  in
position 1.

3.

Route  the  RED  and  BLACK  wires  toward  the  sill  plate  location.  Follow  the  same  path  as  the  factory  wire
harness.

4.

Continue to follow the factory harness through the firewall. To pass the RED and BLACK wires through, it may
be necessary to drill a hole in the firewall. If so, be absolutely sure that there are no components that could be
damaged by drilling. After the hole is drilled, insert a grommet to protect the wires.

5.

Route the RED and BLACK wires along the factory harness towards the battery.

6.

Install a 5 amp fuse block (user supplied) on the end of the RED wire.

Note:

Remove the fuse from the fuse block before connecting any wires to the battery!

7.

Connect the fuse block wire to the POSITIVE (+) terminal on the battery. There must not be more than two (2)
feet  of  wire  between  the  fuse  block  and  the  battery.  As  the  wire  between  the  fuse  and  the  battery  is
“unprotected”, do not allow this wire to come in contact with any other wires!

WARNING! All customer supplied wires that connect to the positive terminal of the battery must be
sized to supply at least 125% of the maximum operating current and FUSED at the battery to carry
that load. DO NOT USE CIRCUIT BREAKERS WITH THIS PRODUCT!

8.

Connect the BLACK wire to the factory ground, adjacent to the battery.

YELLOW (Back Light Control)

Connect the YELLOW wire to a +12VDC source that is activated with the vehicle’s ignition switch.

Connecting the MPC02 Communication Cable...

1.

Insert the Communication Input Cable into it’s port as shown in Fig. 1. Be sure that the BLUE wire is located
in position 1.

2.

Route the Communication Cable towards a B-LINK component (i.e. the B-LINK lightbar).

3.

Strip approximately 1/4” of insulation off the ends of each wire.

4.

Connect the BLUE and GREY wires to the component as shown in the following diagram.

5.

The WHITE and BLACK wires will not be used.

Connecting the MPC02 Auxiliary Input Cable...

Note:

The MPC02 Auxiliary Input Cable is made up of four (4) color coded wires and provides two
(4) auxiliary Inputs.

1.

Insert the Communication Input Cable into it’s port as shown in Fig. 1. 

2.

The wires are coded as follows:
