i have know what box it is and the clips i need to get the box off. But can someone help me out on what the pcm looks like? The two connectors are blue and green that plug in, but the silver box is the pcm right? thats what i need to send in for a tune correct?

In this pic when i take out those two connectors (green and blue) the silver pcm should just be able to lift right out?

 

when you take the black cover off, you will see the silver clip on top of the PCM holding it in..

and the small bolts require a 7mm socket...

 

You have 3 options. a Green Plug. A Blue Plug. and a Silver Box.

hmmmmmm.......
My guess would be the Silver box, IS in fact the PCM as stated in the pic. and yes, when you unhook it, it comes out.

 

That right there is the PCM
That is what is needed

 

haha ok yeah i feel like an idiot....

 

it won't hurt anything to leave the neg battery unhooked for a day will it?

 

Nope. 7mm or 9/32" whichever you have.

 

I love how easy it is to get to and change. Didn't realize that it's RIGHT THERE until I needed to swap one out.

 

yeah its prob very simple and im just freaking out since i have never messed with it. Awhile back i was working on something on the truck and f'd up alittle and since then ive been kinda very uneasy with some stuff

 

just went out and did it, damn i feel stupid asking about it
