how many times do I have to tell you that there's no real difference between a non-turbo and turbo swap? the electrical system between the two cars of the SAME year are the SAME... the only time you do any special s*** to the electrical system is when you start adding aftermarket bulls***... in otherwords, you can take an MSP ECU and plug the s*** into any 2003 protege with a 2.0 engine and it'll work with NO issues as long as you have the stock turbo (and its related s***) installed... many have done it and it works
sure the MSP doesn't have cruise control (thus there's no wiring for it on the MSP), but wtf does that have anything to do with getting the engine to run? it's not needed and that's the ONLY difference in the MSP engine wiring harness and the P5 one
the MSP isn't some fancysmancy special car like the MSM and MS6 are... mazda just used off the shelf parts, put them on the car, shipped it here and had a turbo kit installed after the cars got off the boat... they didn't spend ANY money upgrading a damn thing in the engine or tranny other than the LSD and the s*** needed for the turbo oil return line... in otherwords, when the MSP left the docks in japan, the only thing different under the hood was the radiator, intercooler, and the addition of an oil cooler... pratically speaking it was the same as all the normal proteges before the turbo got installed on our docks
