98 TJ PCM Schematic

Does anyone know where I can find an accurate schematic of the Powertrain Controller Module for the 98 TJ Wrangler?

Thanks but...

I appreciate the effort, but I already have the Factory Service Manual for my 98 TJ. What you sent was a wiring diagram, what I need is the schematic of the internal components of the PCM.

There's a guy in my jeep club that has an ECM for 100 bucks from a 97 4.0 auto.

Ecm?

Is an ECM the same thing called out on the Chrysler wiring diagrams as the Powertrain Control Module?
