im doing a Explorer 5.0 engine/tranny/efi swap in a 90 F250 I have as a project. it is all out of a 98 Explorer but due to the PATS, I used a 96 PCM. I have pretty much everything done and the engine runs great and the truck moves but I cant figure out how to get the PCM to read the vehicles speed. without it im stuck in 1st gear.
the tranny has the OSS on it. according to my EVTMs, the 96 PCM uses the OSS to control the tranny...

but then I see this that shows the VSS and doesn't seem to control the tranny. it shows it going to the same harness as the tranny (C116 connector). I would think if it was going to the rear axles VSS, it would go through the C115 and show it going through numerous other connectors getting there

the 98 seems to use the OSS also...

... but seems to also use the VSS on the rear axle.

I have the OSS hooked up and none of the wiring to it seemed to change between the 2 years. The F250s 10.25" axle has a VSS on it just like the Explorers 8.8" axle. Ive tried wiring to it but nothing seems to work. Do I need to connect on to it and is there a way of not using the ABS module?
