Civic HX Lean Burn "Econo" Light

[firehawk618]

It's just a stupid upshift light, sorry if I wasn't clear on that.....

There's no eco light capabilities in our HX ecu's in North america unfortunately.

The pin that would light up the eco light instead is programmed as a shift up light.

And I bet you are correct on your white plug / up shift light theory.

My LX did not have a white plug back there at all. It had a green one instead.

cool man. thanks. just curious though. what is the 4th wire? it will work without it?

[firehawk618]

I'm fairly certain that 4th wire is to dim the light at night when you have your headlights on.

For your upshift light I am showing the following:

Pin 1 = Red wire > dash lights
Pin 2 = Red / Blue or Red / Green > ECU upshift pin
Pin 3 = Black > ground
Pin 4 = Red / Black > dash lights
Pin 5 = Yellow > power

you rule man. been trying to figure this **** out for a year

[firehawk618]

Any ? just let me know, I have all the schematics and had to do basically what you're doing for that light.

It's not for dimming as it is a constant color.

I Was googling trying to find a low voltage sensor, basically something with an independent power source to illuminate at a programmed low voltage. Anyways ended up buying a cheap $7 tiny volt meter with an independent power source to wire to my secondary o2 sensor readings. It's small enough to hide in plain sight.

I lack the engineering skills to create a sensor to illuminate at less than .9 volts

I assume you don't have an ultra gauge?

Nope, keeping it simple and cheap
