Hey guys jus wanted to know if anyone has a wiring diagram that would help in wiring the MS to the factory ECU harness???I want to keep it as close to PnP as possible.....And also i noticed the factory S5 has some kinda fuel pump resistor that changes the voltage to the fuel pump depending on RPM, would i have to modify this in anyway to have the MS run the fuel pump??Will i also be able to tune for power w/out a wideband O2 sensor...i noe its not recommended or could i at least tune it for daily drivability until i get one???
Would i still be able to run all the factory gauges as well??
I know these are a lot of questions but some help would be greatly appreciated

Future plans are to put 50mm ITB's(Homebrewed)after i get the hang of tuning the MS this is the main reason why i bought the MS!!!
