1 Full Sweep Minor Gauge Wiring: Notes on Senders: Temp Hi match/vdo 150C: Normally used in Oil temp, F. Temp Low match/vdo120c: Normally used in water temp, F. To test the gauges work (oil, fuel, temp): 1) Disconnect the input (S), or leave S open, the gauge needle will go all way to the right (or all the way to the left). 2) Connect the S to the ground, and the gauge needle should go all way to the left (or all the way to the right), the opposite of step #1. 3) If above two steps are true, then the gauge works. 4) For advanced testing, using a resistor around the middle of the gauge range, and the needle should respond by going in the middle of the gauge.

3 Half Sweep Minor Gauge Wiring: I battery or +12V input. L LED illumination, for back lighting, dimmable. S signal input; connect it to B when it's a voltmeter. G ground Standard Input range: Oil Pressure: Ohms, show PSI Fuel level: GM type: 0-90 ohms (E F). Or VDO type ohms (E F). Temp: ohms, F Volt: V To test the gauges (oil, fuel, temp): 5) Disconnect the input (S) or leave S open, and the gauge needle will go all way to the right or all the way to the left. 6) Connect the S to the ground, the gauge needle should go all way to the left, or opposite of step #5. 7) If above two steps are true, then the gauge works. 8) For further test, using a resistor around the middle of the gauge range. The needle should respond by going in the middle of the gauge. Page 3 of 12

4 Warning: Take your time with the instruction manual. The better you understand the concepts, the faster you'll set up the gauges properly. To activate and access the configuration menu, Touch the front when the pointer start to move right upon powering up. Keep pressing it until the pointer goes back to zero and the LCD screen lights up again. Allow at least 3-5 seconds. Speedo and Tach Wiring: Red (1) : Power +12V Black (5) Ground Green (4) LED illumination Blue (7) Signal Input, for all senders. The connections below show optional features: Yellow (8): Shift #3 (or Speed) warning, uses a 400 Ohm internal resistor. The internal LED will light when the speed or rpm limit is reached. The output will change from 12V to 0V when the needle passes this set point. Brown (3): Shift #2, uses a 400 Ohm internal resistor. Connect an external 10K resistor to get 12V to 0V to light the LED when this set point is reached. Dk Gray (2): Shift #1, with 400 Ohms internal resistor. Connect an external 10K resistor to get 12V to 0V to light the LED when this set point is reached. White (6): Remote reset input, optional. Connect to +12 volts via external switch. Page 4 of 12

5 Switch Selections: Input type Switch select Speedo, hall effect sender (logic input, square wave, 12V) 110 Speedo, magnetic sender (analog input, sine wave, 2.1V min.) 111 Speedo, S1 can set to 0 if not working at high speeds 0xx Speedo, S2 can set to 0 if reading not stable x0x Tachometer, Ignition coil or W terminal (high voltage) 110 Tachometer, magnetic sender (analog input, sine wave, 2.1V min.) 111 Tachometer, multispark tacho output (MSD ignitions, 2.1V min.) 000 Tachometer, S1 can set to 0 if not working in high RPM 0xx Tachometer, S2 can set to 0 if reading not stable x0x Notes: The default pin setting is "000", and works in most instances. If the pointer isn't stable in any application, switches 1 and 2 can be reversed to experiment with the compatibility between the source and the gauge. S3 should NEVER be on "1" when the input (blue, Pin 7) is connected to a coil ignition. Damage will occur. Coil ignitions can have a 400V spark signal that will damage the gauge circuitry if S3 is on. Therefore S3 should normally be set to the "0" position. Page 5 of 12

6 Tachometer Setup Menu The default setup will show an hour meter on the digital display. However there is an optional display for RPM on the LCD. Push the button quickly to toggle between hours and RPM. To activate and access the configuration and calibration menu: 1. Turn on the power, touch button as the pointer start to move to right, and hold the button. 2. The LCD illumination will confirm set/reset touch switch is working. 3. Hold button at least 3 seconds until Set S1 is displayed. 4. Push button momentary to scroll through each menu (below) in turn: Set S1 Sets shift light #1 RPM Set S2 Sets shift light #2 RPM Set S3 Sets shift light #3 RPM Set PPR Set Pulses Per Revolution calibration 5. will go each above sub-setup menu. Set S1 Sets shift light #1 RPM 5 digits xxxxx Flashing digits can be set. Use the push button to change each digit All digits flash after last digit is set Push the momentary button while digits flash to confirm settings LCD returns to hour meter function Set S2 Sets shift light #2 RPM 5 digits xxxxx Flashing digits can be set Use the push button to change each digit All digits flash after the last digit is set Push the button momentary button digits flash to confirm settings LCD returns to hour meter function Page 6 of 12

7 Set S3 Sets shift light #3 RPM 5 digits xxxxx Flashing digits can be set Use the push button to change each digit All digits flash after the last digit is set Push the momentary button while digits flash to confirm settings LCD returns to hour meter function Set PPR Set Pulses Per Revolution calibration, only. 5 digits xxxxx Flashing digits can be set Push button momentary to increment each digit in turn. All digits flash after last digit is set Push the momentary button while digits flash to confirm settings LCD returns to hour meter function If an error shows, it mean the data is out of range. The PPR range is only. The higher number you set, the lower reading will be on the display, and vise versa. For example, if the PPR setting is 8.0 and display shows 1000 PRM, then changing the setting to 4.0 will make the display show 2000 RPM. Notes on pulses per rev for different engine types: You have to know pulse/rev in order to calibrate the tachometer. Here are some hints: Gasoline 4 stroke engines. 1 cylinder engine (motorcycle): 0.5 pulse/rev 2 cylinder engine: 1 pulse/rev 4 cylinder engine: 2 pulse/rev 6 cylinder engine: 3 pulse/rev 8 cylinder engine: 4 pulse/rev 10 cylinder engine: 5 pulse/rev 12 cylinder engine: 6 or 3 pulse/rev On modern 4 stroke engines with no distributor, the PPR is usually doubled. On two stroke engines the PPR is usually single pulses per revolution. Page 7 of 12

LCD returns to total ODO. The speedometer process is required and is important. The gauge default is pulses. Increasing the number will decrease the display reading. For example, if the setting is reading pulses per minute, the gauge reading is 60 mph, changing the setting to (increase 50%) will change the display to 40 mph (50% decrease). See the formula below. Don't exceed the maximum setting of pulses. Formula: New reading = old reading x old setting / new setting; Or: New setting = old setting x old reading / new reading (correct MPH) Solving Speedometer Error--You can test the speedometer by checking against a known speed. The easiest way to do this is to download a GPS speedometer app on a smart phone. Many are free. The difference between the actual speed and stated speed will determine what number to use to set the speedometer. For example, if the default setting of pulses equals (displayed) 60 mph, and you find the actual speed is 140 mph (speedo reading too low), then you can use the following calculation: x 60 / 140 = 6857, and then set the pulse count to 6857 and your speedometer will be accurate!

10 Speed Calibration method 1: (same as above) To calibrate the speedometer, have a friend sit in the passenger seat and open a GPS application on their phone. Find a road to safely drive your car at a steady 50mph. At 50 mph, note the reading on your new speedometer (speed-a). PPU (new setting) = 50 x / speed-a Got to SetPPU to set the correct pulse number (X) Speed Calibration method 2: Purchase our GPS Antenna unit, The GPS Antenna works at a higher receiving (10HZ) rate than a typical cell phone, and is able to give more accurate data at high speeds or changing speeds. Check the website for speedometer compatibility. For most speedometers, the GPS antenna automatically converts real speed inputs from GPS data into the default pulses that can be read by our line of speedometers. Speed Calibration method 3: DtSPPU Drive to set pulses per mile calibration. LCD display 5 digits and toggle 0xxxxx Drive vehicle exactly 1 mile--using road mile markers are the best option Stop car after driving LCD returns to total ODO reading Notes: 1. In older cars, the typical setting is 8,000 pulse/mile 2. the maximum pulse count is 64, If you don t drive within 5 seconds while in DtSPPU mode, the menu will quit Page 10 of 12
