where are these located and what do they look like

doin turbo convesrion on my xr3i with ofac managment and dont no what the frst one looks like

 

They are located on the right hand side of inlet on number 4 runner theres a boss for it to fit into, Looks like a cosworth ACT sensor with an injector plug on it, black or brown iirc. If it has a white circular plug then its a xr2i/xr3i sensor.
