I am 99% sure that is the upshift light that only the VX(or CX?) models make use of.

Oh...like to help with the fuel and economy type of light...hmmm...i wonder if i could hooK up my aftermarket tach shifter light into the light itself so it will look OEM

you can just put a small bulb/LED behind that spot where the factory one is supposed to be. then wire that in place of your shift light

It is indeed a shift light. Not sure exactly how it works but uses engine RPM and load to turn on. My 92 CX had it

Heik,
I had a friend that she had a CX and the shift light would come on with RPM. If I remember , the light came on about 4K.
Nice feature if your concerned for gas milage .

4k holy crap :shock: how does that save gas?

the only time my car sees above 2k is in 5th gear at cruise speed

k is really not that high. There is a lot that factors in fuel economy.
We are here in South Florida , Mia , 305 and the weather is hot and the humidity is high. The car has to rev to move with the super dense air and moisture.

Mine would stay on with low load at high RPM but when you either gave it more gas or increased load it would shut off. I would think that it would somehow work off of the TPS and MAP sensors if it is not only RPM but LOAD dependent.

Something to think about. Hmmmmm. We learn something every day.
Didn't think about that.

It works off an output from the ECU, but you can simply put power to the wire and the light will come on. If you have an adjustable RPM switch, you can hook it up to that pink wire and you're good to go. Bulb is already there.

On a regular cluster, you can take some paint thinner and clear out the blacked out slots and then push pins into the harness connectors to use as lights for whatever you want. Trace the connections printed on the flexible circuit board from the bulb to either common power, common ground, or to an empty pin on the cluster harness. I have a VTEC light lol. I plan to add an LED to change the light's color when the IAB's switch on.
