My civic has a canister with a SWITCH ON THE TOP OF THE CANISTER.... I swap the tranny from auto to 5 speed so I swap the engine harness for a 5 speed harness and a P28 Hondata.... The 5 speed harness and the P28 do not used a canister with a switch.... CAN I JUST KEEP THE CANISTER WITHOUT CONNECTING THE SWITCH OR DO I NEED TO SWAP ALSO THE CANISTER AND VALVE FOR ONE WITH OUT A SWITCH?
