I got a 93 miata thermosensor and it has 2 connecter posts and my 94 rx7 sensor only has 1, did i get the wrong sensor or is there a way to hook up the 2 post sensor?

Sounds like you have the wrong part...I recently did the install and it had only one connector post. Btw...you need the miata thermoSWITCH.:)

sorry nevermind i had the part store cross ref the above part number and i got the wrong sensor

i know this is old but what do yous guys do as for the plug?? because the miata switch is a different style plug?? can you get the plug from older 7's or some other mazda's??

n/m i found it. just so that others dont know you can get the plug from 90's ford probe or early 90's mazda 626 from the junkyards

You can cut the plug off a Miata, or just use a normal bladed connector. I just soldered in a female blade style connector and made sure it fit nice and snug. A miata harness plug would have been nicer.

i was thinking about using the female blade connector but i had a doubt about it falling off in the future....

I pinched mine a little to make is clamp very securely.

Dave

^I did the same thing, and then filled the area around the connector with silicone caulk to secure and insulate it.

Just to complicate the picture, it appears that the Miata thermoswitch is only a "remove original, screw in replacement" situation for the early FD engines. Later model years appear to have a different hole size/threads that the Miata thermoswitch does not fit. Even tho I have a '93, it has a reman engine (? yr), and the Miata thermoswitch does not fit.

That's the first I've heard of that. Mine is a 94, with a reman from 00. The t/s fit just fine.

Dave

There was some talk of the FC thermoswitch being a perfect fit replacement, with no cutting or soldering of any lines. Did anyone ever try the FC switch?

Adam, I'll be the first to try. Can anyone suggest a place to purchase the FC switch (that won't rip me off).

Mike, Please post your results. I am very curious to hear about it.

Thanks :)
