So guys I am trying to find the wire that plugs into the maf sensor. Any help here? I have a 92 with a 3.1 with a front end from a pre 89. Where am I supposed to be looking?

 

It's a MAP sensor on the '92 and it should be mounted on the firewall on the passenger side. Follow the vac line from the back of the plenum.

 

Oh ok so the maf sensor must be from the front end. Thanks that helps!

 

There isn't a MAF on a 90-92, period. If you're getting either a code 33 or 34, the system is referring to the MAP. If your car has a MAF (and chances are it doesn't unless someone did some serious screwing with the engine controls), it will be in the air duct between the filter and the throttle body bellows.
