im putting an obd2a b16a into a obd2b 2000 acura el. the el originally had a d16y8 we took out the engine and harness and put the b16 in with a obd2a harness from a 97 civic. we went to plug the ecu in and found out we had 4 plugs for the ecu plus a green one. the green one hooked up fine. but now we are left with 4 plugs for the ecu. the obd2a engine harness has 3 plugs and the obd2b engine harness had 2 plus one that goes somewhere under the dash. so we have the 3 engine harness plugs and 1 that goes under the dash somewhere. which ones go into the ecu? or do we have to get some kind of jumper harness or somthing. and for some reason when we plug in the ecu we cant hear the fuel pump?
