White (JEGS- Speed Sender) -
Disconnect the mechanical speedometer cable from the
transmission and thread the new electronic sensor onto the transmission. This panel comes with a 3-wire
sensor. If you are using this sensor, the
white
wire is the speed signal; connect this to the speed signal
wire on your gauge. The
red
and
black
wires in the cable are switch power (12VDC) and ground,
respectively.
NOTE
:(Twist all Three wires together and this will provide an additional level of interference
protection.) The speed signal wire should not be routed alongside the tachometer, ignition, or any other
high-current or high-voltage wires.
NOTE: When using in a FORD you will need a 555-41611
The recall button on the speedometer operates as follows:
Once
–
cycles between Trip Mode, Odometer Mode and the clock.
Clock
–
To set the clock push quickly push both buttons simultaneously and release. Use the buttons to
scroll to the correct setting.
While in Odometer Mode:
1. Hold LEFT to enter Recall/Setting Mode
2. ¼ Mile Recall
3. 60 Second Time Recall
4. Odometer Setting
5. Calibration
CALIBRATION
The speedometer leaves the factory with a pre-set industry standard setting of 8,000 pulses per mile.
Chances are that you may not need to recalibrate your speedometer, unless you have changed the
original tire size or the rear end gear ratio.
Note:
Do not attempt to recalibrate your speedometer until after it is working properly, and you have
determined that the speed is incorrect. The calibration procedure will NOT correct a faulty installation or
improper wiring. If you attempt to recalibrate your speedometer without making sure the speedometer is
receiving pulses from the sending unit, the speedometer will display ‘Err’ and default back to the factory
settings.
To calibrate:
Locate a measured mile where you can safely start and stop your vehicle.
By running the vehicle over
this measured distance, the speedometer will learn the number of pulses outputted by the speedometer
sensor during a specific measured distance. It will then use this acquired data to calibrate itself for
accurate reading.
1. There is a small recall push-button in the center of the panel used to calibrate and read all of the data
stored in the speedometer. After installing your speedometer according to the wiring instructions, when
the ignition is on it should immediately display the default screen of 0 MPH, if the vehicle is not moving.
NOTE: You will now need to drive your vehicle to the predetermined measured mile. During this trip, the
speedometer should read something other than 0 MPH. If it does not change, return and locate the
problem before continuing. Otherwise, proceed with the calibration.
