Technical Support Frequently Asked Questions Automotive
Do I need to run a dedicated ground to the control box or gauge from my fuel sender?
No, as long as the sender is properly grounded near the tank, a dedicated ground is not required.
If you have trouble with the fuel level gauge, reading 999 ohms in (SETUP/FUEL/TEST) for example, run a twisted pair of wires from the fuel sender signal and ground terminals and connect to their respective terminals on the control box.
If you have terminals “S” & “I” on your sender, disconnect the wire from “I” terminal, select 63VET for fuel sender.
If I disconnect the battery will I lose all my settings?
No, our gauges and control box-systems have built in flash memory, so settings will be retained. You will need to reset the clock time, however.
May I shorten the wires from my oil, water and speed senders?
Yes, wire length will not change the readings.
I only have 2 wires from the stock speed sensor on my transmission where do I connect them?
Connect them to the SPD SND and SPD- terminals. It doesn’t matter which wire goes where, as long as they are not shared with another device.
Do I need the engine running to do a Speed CAL (AUTO CAL)?
If performing a SPEED CAL (AUTO CAL), the switch (SW1) must be pressed while starting the engine. Once the engine is running, the switch (SW1) may be released.
Can I replace the stock senders for water and oil in my LS motor with yours?
No, most likely your ECM/ECU requires the stock senders remain. You can install the supplied senders in addition to the stock units, or purchase our BIM-01-2 to get SPEED, TACH, ENGINE TEMP, OIL PSI (3-wire sender required) and other information from the OBDII diagnostic port (depending on application).
My ECM/ECU only provides a single wire each for speed and tach signals; how do I connect to my new instruments?
Connect the ECM/ECU speed (VSS) output wire to SPD SND on our control box. Connect the tachometer output wire to the TACH terminal on our control box.
The turn signals on my gauge face don’t light, even in DEMO mode what is wrong?
In the Setup menu, go to DISPLAYS - select TURN REMIND and set to GAUGE. This will activate the turn signals hidden within the gauge faces. If OEM is selected, the gauge-face indicators are inactive.
How do I change the settings on my gauges?
When on our website, click on TECH INFO for a full list of installation and setup manuals, which will walk you through the setup process.
What size wire do I need to wire up my gauges?
20 gauge wire is sufficient for most wiring on the gauges. 18 gauge wire is recommended for the fuel sender wiring to ensure the resistance of the wire will not affect the fuel ohms reading.
Can I put my gauges into DEMO Mode?
On VFD and VHX systems, press and hold switch 2 (SW2) while holding SW2, turn the key ON. To go back to normal operation simply turn the key off. For HDX and RTX, the DEMO Mode can be accessed through the setup menu.
