ELECTRONIC SIGNAL PROCESSOR (ESP)
INSTALLATION INSTRUCTIONS
1
 Disconnect batteries. Do not reconnect battery power until system is
fully configured to avoid risk of shock or fire.
2
 Mount the ESP box on the driver's side fender area. Box can be mounted
anywhere but should kept away from the exhaust, so that it is not exposed to
extreme temperatures. ESP can be exposed to general under-hood
temperatures without damage.

 CAUTION
 Tools may be required
 Shown in picture
 Maximum temperature to ESP should never exceed 125C (257F).

The group of 5 wires is connected as follows:
 Ground – The brown wire should connect to a clean ground in the engine such as the battery
negative terminal or a factory ground bolt.
 Power – The red wire should connect to a constant battery positive terminal that is not turned
off with the key switch. An under-hood fuse box or the battery positive cable is a possible
connection.
 Wire should be fused so as not to exceed 3 amps. If the circuit does not have a fuse, or the
existing fuse is higher than 3 amps, use an inline fuse.
 Ignition – The pink wire should be connected to a circuit that switches on with the key switch.
The under-hood fuse box is a possible location for such a circuit. If possible, this should be a
circuit that stays on during engine cranking, as you may encounter a troubleshooting situation
where you need to monitor gauges while cranking.
 Ignition wire should be fused so as not to exceed 15 amps. If the circuit does not have a
fuse or the existing fuse is higher than 15 amps, use an inline fuse.
 Dimmer – Connect the green wire to the factory gauge dimmer circuit by either tapping into
the in-cab fuse block (see the next step for getting the wiring into the cab), or by connecting
directly to the wire running from the dimmer on the headlight switch.
  Mode – The blue wire connects to the optional mode button, and is used to customize the
dimmer curve to match the factory lighting. Install a normally open (N/O) momentary
switch between the mode button and ground.
4
 Run the remaining wires from the ESP into the cab. Look for existing plugs in the firewall, such
as the plug for a clutch-pedal linkage on an automatic transmission equipped vehicle. If the plug is
too large, drill a hole in the plug and add a grommet.
5
Route the three (orange, white, and black) to-gauge wires through to the A pillar and stop there, or
continue through to the overhead rearview mirror if the gauges are to be mounted there.
