Mystery engine wire plug after replacing head gasket

Hello,
I recently replaced the head gasket in my 95 Tacoma and can't figure out where one of the engine wire plugs goes. It's a two prong plug that branches off around the throttle body and is about 6 inches long. The truck starts without it, but only runs for about 8 seconds before it shuts itself off. Any ideas as to where this may go? I can't seem to find anything so I'm assuming its under the intake out of sight. Any ideas would be greatly appreciated. Thanks!

 

A picture of the connector and motor size might help.

 

I can try to post a better pic when I get home but I believe it’s this one here. The engine is either a 2RZ-FE or a 3RZ-FE manual transmission with nothing fancy (no AC, power windows etc)

 

That motor doesn't even look like its been disassembled and reassembled. I'm so glad I live in a salt free zone.

 

That could likely be your IAC valve plug
