Trouble Shooting Help

[scotty144]

Hello All, I had my new HFS-3 installed yesterday on my STI and unfortunately the unit doesn't appear to be working. Followed all the wiring directions with exception of the blue wire attaching to dimmer option. Did eventually try feeding it a 12v signal but it made no difference.

There is no power or signal being sent to the gauge. There is power to the controller and to the pump located in the trunk. Turn key on, pump runs but will not shut off and no signal or lights on the gauge.

Opened the controller and the fuse looks fine.

Any suggestions?

Thank you

Scott

The problem was caused by the gauge and grey harness plugged into the wrong socket.
Once rectified, system is now working good.
