From the Electronics Forum at LS1.com...

Under the hood on the passenger side you'll see the PCM. Its far back towards the windshield. You'll see a lot of wires going in to a couple of harnesses that plug into it. Theres 2 10mm bolts that hold it in. Remove the 2 7mm bolts holding the harnesses in and set the harnesses aside. Then remove the 2 10mm bolts holding the PCM secure. Now you can turn the PCM sideways so that the part where the wires went is now facing the passenger fender. The PCM will now lift right out with ease. You could leave the harnesses attached but it causes you to have to struggle to get the PCM out of its cubby hole. You'll now see a rubber grommet in the firewall. You can fish your wire thru here. Now inside the car, go to the passenger kickpanel, up behind the glovebox you'll find your wire. Its usually easier to remove the kick panel to find the wire. Anytime you add any wires to the battery, make sure you fuse them within 18 inches of the battery.

 

thank you very much LS1 RULZ now to go and finish this installation
