Default Where is the ECM located ?

97 sport... I thought it was under the drivers seat.. Pulled the seat and noticed the unit has a sticker on it that says "module for "air bag"...

Is this also the ECM / PCM ?

Under the hood on the driver's side between the air box and the fender. Has 3 big plugs going to it

The book's wrong! #1 is at 5:00, viewed from the side. 153624 clockwise.
I RECOMMEND 280 155 746 INJECTORS, FOR YOUR 87-90 JEEP. 4 holes are better than one, and they won't leak out the middle,(like stock injectors can)
