12V BATTERY
INSTALLATION INSTRUCTIONS
FULL SWEEP
ELECTRIC FUEL LEVEL
2650-1136
1. Check that you have all parts required for installation, and that the engine is cool.
2. Disconnect the negative (-) battery cable.
3. Gauge mounts in a 2
5 ⁄ 55
8
⁄⁄ ” hole for 2 5 ⁄ 55
8
⁄⁄ ” gauges, and a 2 1 ⁄ 11
16
⁄⁄ ” hole for 2 1 ⁄ 11
16
⁄⁄ ” gauges.
4. Connect the purple sender wire to the fuel level sender. Existing wires may be used, or route the
purple sender wire to the fuel tank.
(The stock fuel level gauge, if equipped, must be disconnected.)
5. Connect the white wire to dash lighting or switchable 12v light source.
6. Connect one of the black wires to a good ground. (Either black wire, does not matter which one)
7. Connect the red power wire to a switched +12v source.
8. Reconnect the negative (-) battery cable.
1. The brown and black wires are used to set the sender type. The gauge ships pre-programmed to read GM 0-90 ohm senders.
If using a 0-90 ohm GM sender, separately insulate the ends of the brown and black wires with electrical tape, and coil them up
under the dash.
2. If any other sender type is required, connect a Radio Shack 275-1556 or equivalent momentary switch to the black and brown
wires (see illustration above), or alternately touch the stripped ends of the black and brown wires to simulate pushing the button.
3. Press and hold the button, and apply power to the gauge. The pointer will sweep back and forth stopping momentarily on each
1 ⁄ 11
8
⁄⁄ -tank mark, indicating that the gauge is in sender select mode.
4. Allow the pointer to move to the appropriate location on the dial per the sender select chart (see next page), and release the
pushbutton. The pointer can be bumped to the next position by momentarily pressing the button.
5. Remove power from the gauge to store the new sender type by turning off ignition switch.
6. Re-apply power to the gauge, and confirm that it reads the proper fuel level. If the proper fuel level is not read, return to step 3
and recalibrate. If the proper fuel level is still not indicated, perform Custom Sender Calibration.
7. Remove power from the gauge by turning off ignition switch.
8. Remove switch if used, and tape the ends of the brown and black wires, so they can not touch.
9. Coil the wires up under the dash.
