hey im new and i have a 91 sas ext cab pickup with a 3vz and i recentley jus bought a supercharged 3.4 for a screamin deal of $850 out of what i was told a 97 4runner with a auto. i jus bought a harness and ecu but i dont know what it came out of the ecu#8966-04050 and i when i plug them into the ecu im missin 2 smaller plugs

 

https://www.yotatech.com/forums/f160/ all of that is covered in the 3.4 swap section that i just posted the link for. Read all of the write ups atleast twice. All your questions can be answered just by reading. On my swap i used the 3.4 pwr str pump, 3.4 alt, 3.4 ac compressor.

 

ecu help

 

this wat im talkin about

 

Wow, that's an amazing deal. Even $850 for a used s/c setup alone is a good find.

 

ECU 89666-04050 is from a 9 of 03 to 9 of 04 tacoma. The plugs you are missing are going to come from the dash harness.

 

could u tell me if it was a auto or man?

 

According to www.toyodiy.com 89666-04050 is for an auto trans.

 

well tmz just iformed me that i cannot use my harness cuz it requires a sensor for the gas pedal that i do not have and it from a 2003-2004 tacoma and i have a 97 4runner with a mangled harness and it didnt come with a ecu

this is on ebay so im wonderin if it will work with my old harness but its from a 2x4 4runnner and mine is a 4x4 4runner
