Oops, the switches are labeled correct. Guess my eyes aren't what they used to be. Post edited.
I see what you mean about Ken's thread. I was looking at the first post/photos. Appears he swapped housings later on. It's confusing.
Something I've never bothered to figure out is the story on the upper switch. It's supposed to disable AC operation when coolant temp reaches 234 F and is connected only to the AC amp but is not labled as switch number 2 in the TEWD. It *is* labled as such in the TSRM though. Plus that switch shouldn't control fan operation yet mine does, along with the other switch on the blue connector. Worse, the switch that controls fan operation is labeled as number 2 in the TEWD when it should be labeled as number 3, which is not shown anywhere on the schematic.
I dunno. Appears it took Toyota time to get all that sorted out and the books don't match up. Whatever the case I use the 234 F switch as a high temp alarm so I don't have to watch the gage. I wired a Mallory Sonalert to that line under the dash to let me know if coolant temp ever gets that high. Been there for years but fortunately has never come on.
