AUX plug inputs for R33 GTST

Postby LukeEmmo » Sat Nov 27, 2021 6:39 pm

Hi all,
Just about to wire up my new Plug in Pro for my R33 GTsT. My tuner advised to also add in An air temp sensor, wideband 02 and an oil temp/pressure switch. Now i have the extra plug already that came with my ECU with pins but im confused about the pin outs and what to connect the sensors to. So in the instructions it suggests for the temp sensors to pin them into an ATI. But on the outputs for the expansion plug it only lists AVI. All sensors are from haltech and came with pin outs and plugs. I have the full 02 wideband kit which is straight forward.

So my question is are the AVI and the ATI the same thing? The way im reading the booklet this is how i would wire. Is this correct?

Pin 1 = 5V To air temp signal wire
Pin 4 = Signal Ground for Air temp

Pin 9 = 5V supply for Oil temp/pressure switch
Pin 12 = Signal ground for the Switch.
Pin 10 = Pressure Signal (from sensor)
Pin 11 = Temp signal (from sensor)

Appreciate all the helpful tools you guys supply. IS very very good, along with all the videos on the you tube.

Did you solve this then ?

I am stuck with the same, Wired the ecu aux input side as guided in the haltech platinum pnp pinout but on software Input selection tab it doesn’t show AVI3 and AVI4,
Wonder if ATI1 and 2 are pin 10 and 11.
