#293432 how is a 94 obd1 gsr swap(map sensor in the harness) into a 92 lx(firewall mounted map sensor) supposed to have the map wired? the wires for the factory setup are ran right into my ecu as my only map wires. and i dont have any voltage out to the map sensor thats in the engine harness. BUT the thing is the car ran like this somehow when i bought it. can anyone give me some info?

#293539 use the factory (to the car) setup, run a vacuum line from the engine to the map...

#293961 off the intake manifold... doesnt matter exactly where as long as it sees vac.
