Truck Repair: Ignition control module., side kick panel, chevy 4x4

Question
I have a 1991, Chevy 4x4, Cheyenne Pickup, 6 cylinder.  I need to find where the ignition control module is so, I can replace it.  Where would I find it on my engine?

Answer
Hello HP,
It is probably behind the side kick panel by the passengers side floor board.
But if you don't know where it is located, I am curious how you know you need to replace it.
Conclusion jumping due to someones guess, can get very expensive for the owner.
And if it is indeed damaged, if you connect a new one, without finding what damaged the old one, and repairing that problem, the new one will be damaged also, possibly immediately.
