47-55.1 Convenient EFI computer location in 52AD?

[Northern 52]

Not sure if this has been asked before but what is a good location for the EFI computer? I have a 2002 crate 5.7 Vortec engine going in my 1952 truck. I pulled a 411 computer form one donor truck and the wiring harness from a second one. The harness was from a truck with the computer located just behind the drivers side headlight on the inner fender. This location on the 52 would be very tight and possibly quite hot. I was thinking of possibly putting the computer under the dash above the heater hole but keeping the harness plugs on the engine side of the firewall with a nice rectangle hole through. Behind the seat, under the seat, are other ideas but I don't really want to lengthen all the wires. Any good options with pictures would be appreciated.

Thanks and Happy New Year to all
