Is the only reason that you are running the s4 Ecu is due to the fact that you are not running an electronic OMP?
If you want to avoid a wiring "snafu",you could ditch the S4 ECU,get a S5 TII ECU,and send it to Pocketlogger.
They make RTEK based Ecu's that do not use an OMP.That would let you use a S5 Based harness and keep the Chassis/gauge harness as S5.It would alleviate the need to change wiring on the car,really.
If that is something that you would consider,here is a link to their site: digital tuning, inc. .
