97/98 transfer case
So I bought and installed a '98 transfer case in my '97 Explorer. The '98 has no provision for the '97 speed sensor.
Oops.
After a lot of searching, I know the following:
'98 Explorers use the rear ABS sensor at the axle for speedometer, Speed Control Servo, radio volume, GEM, etc.
'97 Explorer The VSS has 2 wires coming from it, one is grounded in the PCM. The other goes to the GEM, as well as the speed control servo, and also to Pin 33 of the PCM.
Does the VSS in the '97 transfer case send the same square wave as the ABS sensor in the axle?
Could I splice the VSS sensor wiring into the rear ABS sensor on my '97 in order to make the speedo and cruise work?

Shows 85 views, not bad compared to other threads started at the same time. I think it's a matter of "no one knows".
Do you have a way to measure the output, to see the "square wave"?
I suppose if you hooked it up as you suggest you might risk damaging other components.

I'm wondering if anyone has the equivalent diag procedure for the speedometer speed sensor? Is it's output the same?
