Default do the pr4 and pm6 have the same pinouts?

ive tried searching everywhere for pinouts on the pr4 but no luck. i know they come from the same gen of cars but i need to know if the wires are the same. im helping a frind do the dpfi to mpfi swap and he got a pr4 90-91 teg instead of a pm6 that all of the site tell you to use. so i need to know if it is possible to use the pr4 in this swap we are trying to finish it up today and all is left is the wiring thanks in advance if you can help

Some PR4 have internal PA sensor (91 ECUs) and some PR4 have external (90 ECUs)...

PR4-A01/A02 - External
PR4-A10 - Internal
