The speed sense wire is in the instrumant cluster wiring and is GREEN / WHITE stripe. The problem is there are 3 of them. Anybody know which pin # to use? What is the best way to test? Thanks.

The wire is also available at the radio's harness as a GREEN / WHITE. I believe it is in the smaller of the two plugs at the radio. Measure for continuity between the two similar colored wires at the radio and the cluster. If you measure the wire on an A/C voltage scale while the vehicle is moving you will get a varying reading.
