H22 ECT switch wiring!?
Ok, on the H22 there are 2 ECT switches; ECT switch "A" is in the thermostat housing (where the lower radiator hose connects to the engine), and ECT switch "B" is in the front waterneck (where the upper rad. hose connects to the engine). MY QUESTION IS: How do I wire up ECT switch "B" -the front one, I need the ecu pinouts, I lost my prelude chiltons book!

Re: H22 ECT switch wiring!? (Hondaddict)
When I had my wiring done, the person didn't add the switch b, the one on the waterneck, do you really need it? Right now I have one check engine light which is for the iacv, and according to helms it could be a possibly cause because of the ect. I have a 98 jdm engine, but on my cousin prelude which is 98, her front water neck doesn't have a sensor there, and I notice all the h22a4 doesn't have it eitheir. If its need, I too need to know how to wire the switch b.
