Mopar PCM help request

[Sare, Terry]

No scanner unfortunately. The wiring diagram covers about 20+ pages in the
Factory manual for 98 RAM Pickup. What are you looking for?

7812 is weird baud rate. If I put a 485 transceiver on the bus will it
correctly translate the signal to TTL? Do you have any good references to
read for this bus?

It is similar to RS-485 and has 7812 baud rate. BTW, if some kind person
can scan the wiring diagram and upload it to incoming dir, that
would be nice.
