hey iam putting a b18 in my civic and i was wondering if all the wires under the hood will work with out me moding ?? will all the sensers work or do i need to rewire the entire thing ?? sorry first swap and thanks for any help

 

what year motor and what year civic?

 

its a 98 civic ex and iam putting in a 91 b18 obdo from an ls. i have the ecu wiring harness all taken care of but i wasent sure about all the wires to the motor and under the hood. i know it sounds like crazy putting an obdo motor in a obd2 car but i have my reasons. and thanks again
