ok i have a 93 cx with a shot motor. i have a 94 dx auto that im taking the motor out of and swaping. question is. i notice theres only one wire for o2 senser but the dx has 4. can i just swap wiring harness and the ecu or do i gotta get a manule dx ecu?? or can i just keep the same wirring and ecu be fine thanx

 

just swap the engine and use the wiring from the original car.
buy a 28.00 new 1 wire o2s from the parts store

 

just use the stock CX ECU and engine wiring harness... still be slow as ---- either way... JUST SWAP MOTOR, NOTHING ELSE...

 

i know its slow lol but im just wanting a runnig motor in it . lol thanx for the info i just wasnt to sure
