If you are not using air con (aux 3) or purge canister (aux 4) you could put the tachometer on one of them, alternatively you could put it on the expansion connector (aux 8). Then assign tachometer to that output in pc link 

HTH,

I suspect you will also have a high-level tacho in that car so it may either need to be modified or a tacho booster in between ECU & tacho.
