Rsr air shift module. His harness for the injectors piggyback to the msd piggyback so the cut won't reset the module. Key eliminator. Pcv with pti, that worked well with turbo. Wego3 and tail for ecu flash. Maybe more. I cut a lot of stuff out like the signal and lights. Added switches upfront to cut on water pump and air shift. I have a lot of hours in that rats nest. But going to us it on another project till I get this standalone finished. You would be my first choice though.
