where does this plug go again?

[rdyzz]

so i had mr220v from the beams and mr2oc.com site mate my smallport 4age and beams 3sge harness together. he left some of the 4age plugs intact, and i forgot where this plug goes, im thinking its a plug for a water temp sensor or EGR temp sensor. if you guys know please lemme know, thanks.

just went and looked at my silvertop and I don't have one... but i think my 4af did and I thought it was some sort of water thermo switch. it only has 1 wire going to it... my rx7 had one that looked like that and it was a coolant switch for the AC system (??) it no longer has it....

Radiator fan?

[rdyzz]

its part of the engine harness, im starting to wonder if it has to do with the egr system

Don't know how consistent Toy is on connectors on their engines but on my 4AFE that plug connects to a sensor on thermostat housing.

I believe that is for the back up light switch which is in the tranny right in the same vicinity as all of the sensors in the thermostat housing on a 4A engine/tranny.

what color is the wires going to it? i think back up is red/black & red/blue.
