AEM EMS part #30-1070 for swapped cars,30-1030 for factory K cars. ..not 100% sure about the TSX ecu plugs,but Im sure the pinouts will slightly differ if it does plug up.You could use a RSX harness on the tsx engine though.I do not think the ems will suport drive by wire.
Both ems's support :
K20A2
K20A3
K24A1
D17A1
D17A2
