Speedo calibration after gears

Well, it might be wise to correct all the signals. If you grab the wires from the transmission harness connector at the firewall, it should fix all of them.

Mine does not have that speed correction amplifier.

Yes so the only thing is where would I place the calibrator box at? It’s a little unsealed box with circuit boards inside with diodes, resistors and chips inside of it. I think it won’t last too long in the elements. I was thinking connecting it at the transmission and running the wires in through the shifter hole and placing the box inside the car some where in the transmission tunnel. What do you think?

That’ll work just fine. You could do it there, or run your wires through the firewall bulkhead where the factory ecu runs them. Up through the floor may be easier though.

That is exactly what I did with my Speedcal. It's placed under the radio, behind the cigarette lighter area.
