I have searched and read a few posts on speedo's first but not sure still.

My MX83 electronic speedo doesn't kick in initially so I contacted a forum member who could have done the capacitors but he has moved and can't do it.

I have found a complete cluster for sale but the seller will not let me try it out in my car or give a refund if faulty, he will let me bench test it though?

I have a MX83 speedo sender/sensor, a compatible grey connector plug, I have a multimeter, car battery and wires.

Does anyone know how I can set it all up to test out of the car before I buy it please? Which pins on the grey cluster connector to hook up?

The wiring diagrams I have are conflicting with the connector colours/numbers and pinouts and don't help much.
Update:
I have removed my cluster to show the wires and connector. After using the MM on the yellow wire from the disconnected white plug (dash side) It looks like the speedo input wire at the grey connector is yellow with a blue trace not brown or yellow as in the diagrams? Doing my head in!

I have now removed my speedo unit and the circuit looks pretty crusty at the top of the board as shown. This speedo issue might put all the Cressida's off the road :-(
