jdm d15b vtec MAP sensor

I just got finished dropping in my jdm d15b into my 92dx hb. I'm about to connect all the plugs and what not and I saw that the MAP sensor is located on the throttle body (I think thats what its called) on the engine itself. The old engine that was in there before had the MAP sensor on the firewall. The wiring harness that came with the new engine has the plug for the sensor comming out of the harness itself. On the other sensor (the one on the firewall) the cable goes directly to the ecu I think. Do I have to rewire, or will it work if I just use the connector that comes out of the wiring harness on the engine? I'm using the p08 ecu that came with the engine. Thanks for any help, I cant wait to get this baby running

T the vac source into the charcoal canister or fuel pressure regulator line.

T it or go buy a 94+ls throttle body.
