Can someone please tell me where the ECU is located in my truck? I seen tolleyy's instructions on pulling the codes, but don't neccessarily know where the ECU is. Rumored to be under the passenger seat? Can I easily unbolt the seat to look at it, etc.? How can I see the ECU while driving?

Also...I have a suspicion that the Check Engine light on my truck has been disabled (bulb gone). Is there an LED light that will flash on the ECU also, or is it run strictly through the CE light? The instructions seemed to indicate just the light.

Thanks much,
