When I got my S13 most of the components under the hood were stirpped so I am having to replace a lot of components. I was at the salvage yard and happened across this on one of the 240's out there:

(I took the time to clean it up and put a coat of rust bullet on it.

Obviously the plug is broken but I can't seem to find this thermocouple (or whatever it is) mentioned in any of the manuals. Is this an original part for the 240sx? I believe it was in line with the lower radiator hose on an 89 - 90 240sx with the ka-e motor. I'm doing a ka-de swap, is it something I need? Which harness does it connect to and what is it's purpose (beside coolant temperature)?

Thanks!

That is a fan switch for the AC fan. only found on SOHC 240sx.

Excellent, I won't be running A/C for some time so I can omit it. Thanks for the reply! :w00t:
