Where does the wiring for the sensors route? This is for my 1jz swap.

I have the sensors just not sure if they went through the drivers side (charging starting area) harness or the engine harness.

I need to wire them up to the gauges.... thanks for any help!

 

they were on the main fuel injection harness "emissions" harness (or at least, I know the water temp was) which went through the hole on the passenger side.

 

Do you know where the signal gets to the gauge from?
