Default Help me identify these sensors? 99 SC300 VVTi

Hey guys, can ya help figure out what these sensors are? Im doin sort of a hybrid setup using a GE ECU and harness too run a GTE (for emission purposes).

Also the pics of the pressure valve below get a vac line from the pressure canister, but I obviously cant run the part of the valve thats inside the intake manifold. Think I could just hang the pressure valve by the pressure canister and put the vac line on it? CEL maybe?

Thanks guys

The 3rd and 4th pics are part of the EGR system. That's the diaphragm that opens and closes the butterfly damper inside the intake. The static state is fully open (ie. if you disconnect the vacuum line, it stays wide open). Are you running a full EGR setup? If not, I don't believe there is any intelligence to that part of it to worry about; just cap or plug the line that ran to the diaphragm.

My 99 doesnt have an EGR valve or anything. I think your right, I dont see how the ECU would know if thats just a capped off line instead of the valve being connected.
