Put my PCM in the back seat and made a rear seat delete panel which slides out. Not sure if your harness has an ODB++ port but if it does mount it somewhere you can access it easily. I put mine in the middle and connect my diagnostic tool to monitor temp, rpm, IAT, ect..
BTW, my PCM was ordered for a 99 5.7 LS1 Camaro, now that I got the 08 LS2 Vette motor I plan to have the car Dyno tuned early next year. Figure I can squeeze an easy 40hp and get a more optimal fuel curve. In the higher RPM range I feel I am losing torque and power which could be the tune or fuel pump. No telling for sure until she gets hooked up to the Dyno and air/fuel ratio is recorded.
