Hey everyone I need help wireing up the edfc to my Tein flex coilover system.
I had some weird problems with the unit so far. I installed the 3 wires using the battery, The ashtray light, and the center console switch that moves the side mirrors.

The edfc turns on and functions. Everything beebs and lights up and works except the indiglow backlight. Its really hard to see and its bothering me. The weird part is that when i installed it it didnt work, even though i made sure everything was getting power with a voltmeter.

Then 1month later to my surprise the green backlight display is working fine. This last for about 1month and one day the Edfc is beeping. I see the screen it said Rear Left EL. I powerd it off, and turned it on the next day. Now my backlight display doesnt work anymore

Can anyone tell me how they wired up their edfc to work properly. Any idea of whats wrong. What should i be tapping into? Did i wire it wrong?

I called tein and they said it must be a faulty connection. By the way I made sure the brightness was on high. Any bit of information helps. Thank you.
