Thanks for that dave much appreciated

Running a Rb25det S1 Going to running a aftermarket tps sender from nzefi but its only a 3 wire sensor. standed loom has 2x 3wire plugs as see in photo attached . Plug 1 (pin 1,2 and 3) are use for throttle fully open or throttle fully closed. My question is do i need to run the 1st plug?

Do I need to run the aac valve (idle air control valve) with a g4+ plug and play on a rb25det or can the ecu run without it?
