Actually they did. My 1992 VX was originally purchased in Wisconsin. On the instrument cluster to the right of the trunk-open indicator, there is a white outline surrounding an arrow pointing up. It lights up green when you exceed 2500 RPM below 5th gear. According to the owners manual it is telling you to upshift. The VX was designed with a lightweight flywheel and with engine breathing characteristics in order for it to cruise at just under 1000 RPM. Without this shift indicator light, most owners would never cruise that low.

UNFORTUNATLEY FOR ME, the gas gauge went bad and always indicated full, so I had to replace that portion of the cluster with one from an Si. I kept the cluster face though. I can take a picture and post it up if you would like.

If you want to tap into some O2 sensor wires without cutting and splicing, you can use a technique that I came up with for a similar purpose. It will not be so easy to find the parts due to the rarity of the VX however, but what you would do is get a dead O2 sensor, cut off the plug, then find a junkyard VX, cut off the ECU side of the plug. Now wire together all the wires you don't need to tap into and bypass the two wires you need to go to your circuit then back again. Then you simply plug this homemade adapter inline with your O2 sensor.
