Default Installing new pcm..

I ordered a new pcm from westers garage. Some guys on the board told me to make sure I didnt short out the chip by not unplugging the battery and trying to keep static charges from it. What things should I unplug and what are some precautions I can take to ensure I dont fry the chip? Also any pics of the parts I need to unplug would be real helpful!Thanks.

Just remove the negative terminal from your battery when you install it.

Make sure that you get the PCM reflashed and a crank relearn done from the dealership if it is a Brand New PCM.

Good Luck

Remember, ONLY use a GM approved hammer to install it

J/K, it's a pretty simple installation. Why are you replacing the PCM might I ask?

My friend got a re programmed pcm from them and he hasno mods what so ever and once he put that thing in it felt like another truck! With the minimal mods I have I got it figuring tenth to 2 tenths...and you get free updates whenever you want so I figured what the hell.

7mm for the connectors on the top, and a 10mm for the plastic bracket.
