hi, i was wondering if anyone knew what to do with the replacement MAP sensor they give in the kit. Are we supposed to hook the map electrical and vacuum lines into this new sensor and just leave the old map sensor unconnected? Thanks, i think this is for tne MF2 install...

 

The new MAP sensor connects directly to the MF2. You do not disconnect the stock MAP sensor and you still need to use a check valve so te stock MAP sensor does not see positive pressure. How to hook up the MAP sensor is in the MF2 manual.
