JDM wiring/installation questions (round one) - Honda Prelude Forum

I started going over the wiring harnesses for the USDM f22 and JDM H22 today. I got all the VTEC wiring, knock sensor, and secondary wiring figured out no problem. It seems like the JDM H22 is lacking a ECT sensor that the f22 has (apparently, the USDM H22 has it. . .its shown in the helms). The f22 has a sensor right on the neck for the upper radiator hose, but that passage is closed off on the H22. Is this normal? Is the sensor located somewhere else on the H22 (I cant find one)?

Secondly, There is an extra solonoid right above the fuel rail on the jdm h22. Is this another part of the IAC system. It has two vaccum lines and a 2-wire connector, what is this thing?

Any help much appreciated!! Now I just need to lay into that damn distributer. . .

Heh. . .found the answer to my first question in one of my old posts. Guess I can cross that one off the list. . .

"*NOTE: There is no ECT switch B on the JDM H22, just spare back the connector."
