It wouldn't matter that the signal was shared - just has to be shared correctly.

It'd be wise to get the wiring diagrams for each PCM (I found mine on Google).
Check those and confirm the intended circuit each PCM requires..
I'm thinking along the lines of same operating voltages, and then ensuring the PCMs are of sufficient high resistance in the closed circuit state to not draw too much current.
