Question How to remove my PCM?

My new PCM was delivered today from PCMFORLESS and I need to know how long it should take for the swap. What tools will I need? How easy is this?

Thanks.

Should take about 5 minutes. I think you need an 8mm socket, or is it a screw driver? Can't remember. But, there's two bolts on the case. Remove them....pull the PCM out. Unplug the four main plugs. Now reverse the procedure and just plug everything back in; its color-coded for easy install too!

I should know this, but where is the PCM case? Anyone have a good picture of their engine? I believe if you're looking at the engine from the front it is on the upper left side. Is that right?

Its a 10mm socket... You will also need a regular screwdriver to lift the lip on the connections because its hard to with your hands...

I knew it was a small little guy...guess I was thinking too small. I never had a problem with the clamps on mine...but I had to use a flat head on one of my friend's PCMs.

I use a flathead, I'm not busting my my pretty nails just to get a PCM off Facing the engine compartment its on the back left, aluminum box, with a peice of black plastic holding it down, which in turn is held down by 2 bolts.
