Why is my fuel gauge so erratic?

Our PCB reads resistance from the fuel sending unit and converts that to needle movement.  If your sender – or the wiring going to our PCB – is faulty, the needle is reacting to their mixed signals.

How does the PCB connect to my car?

It takes power from your vehicle electrical system and input signals from the sender for each of the gauge functions.  Connections are made with color coded wires coming from harnesses that plug into the PCB.

What is the PCB?

It is the electronic brain in our system.  It takes input as electronic signals from the function senders, interprets them and then sends signals to the stepper motors driving the needles to make them move appropriately.

How do I set the time on my clock?

If you touch the silver button at the six o’clock position on the clock the hands will start moving.  The longer you hold the button the faster the hands move.  When you remove your finger the clock hands stop moving.
