It was EFI...
I read about the VSS line off of the cluster, but I couldn't find anything on the cluster wiring diagram. I've since found a VSS input on the ECM diagram that appears to come from the cluster.
Is this what people have been using to splice into the new ECM? Does the signal have the correct frequency to make the OBDII ecm happy?
Thats the one,most years are green with blue stripe.
