Looking to see where people are putting the PCMs. I cannot fit mine on the passenger side glove box area. The vintage air evaporator box is much larger than stock. Recommendations? It is a PCI harness.
A friend of mine mounted his in the passenger side kick panel opening. He is using an 0411 ECM and had to cut some metal away to get it in. The later model ECM's fit without cutting.
I have seen inner fenders modified with a tray under hood hinge area to slide the ECM in. Remember they are waterproof and GM mounted them under the hood. Just stay away from high heat areas.
On my Chevelle a custom console was built with the area at the front large enough to mount the ECM. The top is removable for easy access.
