I am almost complete with a jdm b18c1 swap into my 91 rs. the map sensor on the car is located on the firewall and the new motor comes with one on the throttle body. i have done almost the entire obd1 conversion and am just lost as to which map sensor to use? should i extend the wires and use the one on the throttle body of the new motor or continue using the one on the firewall? and either way i go, what do i do with the unused map sensor? just leave it there with nothing plugged in to it? thanks in advance for any help.
