Tim, my L98 computer (E38) is wired to the Vehicle Speed Sensor on the side of the T56. Straight from computer to gauge with no resistors.

Thx Sambo,

Is your straight from computer to gauge via the bulkhead connector? And do you also have a ground wire from the gauge as well?

I don't have a bulkhead connector as the computer is inside the cabin, but yes the speedo signal runs straight from computer to gauge. All gauges need a ground in order to function, otherwise there's no circuit.
