FIRST OF ALL I HAVE A 90 LX CIVIC 4DR DPFI AND I DROPPED A 90 LS TEG. i STILL HAVE THE TEG ENGINE WIRING ON IT AND NOTICED THAT THE PLUGS ON THE 90 LX IS LACKING SOME PLUGS. MY ? IS DO I NEED TO SWAP OUT THE LS ENGINE WIRING WITH MAYBE AN SI OR CAN I JUST USE THE LX CIVIC DPFI WIRING. AND I KNOW THAT I MUST CONVERT THE DPFI TO MPFI. IF I CAN USE THE LS TEG WIRING WHAT MUST I DO? THX
