Gen III ECM's

[censo69]

I have a gen III LQ4 6.0l out of a truck, Its now stroked with L92 heads and a LS3 Intake. When I bought the motor it came with the original ecm. I was trying to plan the layout of all the wiring and thought it would be nice to mount the ECM in the blower motor box since its now gutted and I will be running a vintage air unit.



So here are the questions.
1. Where are you guys locating the ecm ? I'd like to not place it in sight
2. Since the truck ecm is gigantic is there another LS1 ecm that is smaller ?
3. A friend has an ecm for a Trail blazer that is much smaller but that is a LS2 ... and I think a gen 4 58 tooth.

Switching reluctor wheels is not an option.

Any thoughts ? .

By the way its going in a 69 camaro.
