Hey guys, sorry for the 3 week delay- I've been busy with school, work, grad school applications, etc.
I did install the yellow box. I tapped into the pin on the ECU for the speedo.. but it doesnt seem to be working.
I think some people were saying something about tapping into the signal behind the speedometer itself? This would require be to take off my gauge cluster, correct? Does anyone know which wire I should tap into for this?
The speedo works, but it's still off by about 12% or so. I probably just tapped into the wrong wire.

RED
YELLOW
BLUE with red stripe
If I remember correctly, the pin on the ECU that was tapped into was a blue with red stripe. The wire from the speedo sensor on the transmission goes all the way to the ECU- it's on One harness (the main wiring harness).
Should I just tap into the gauge directly? Is this supposed to be a Pink wire?

I just crawled under my car and took a pic of the 2 wires on the speedo sensor.

are you 100% sure that this wire is PINK? I'm certain that on my car, the pin A2 is not pink- it's blue with a red stripe.
maybe i'll tap into the wire behind the speedometer cluster

My car is a 1992, so it is possible that the wire color is different, but if you do a search on the "VSS" wire, you should find exactly what you're looking for on your specific model car.

The wire I tapped into was PINK. The yellowbox still isn't recalibrating the speedo for some reason.
Should I just try to tap directly into the wire coming off the speed sensor on the tranny?
