The PCM takes the 5 volts oil pressure signal, converts into class2 serial data and send it to the original instrument cluster. The Crank, Cam and Coolant temp are the main inputs for the PCM from the engine....other than MAF.

I have wire schematics up to 2004 depending on the year, so perhaps I can help with wire colors and terminal number if needed. But don't worry out oil pressure signal. As for aftermarket temp sensor, most go with metic adaptor into passengers rear cylinder head. Same as OE on drivers side.

Hope this help a little.
