LS swap people - Where did you mount the ECU?

I'm swapping an LQ4 into my '79. What's the most convenient spot that still keeps it looking clean? Underside of the cowl under the dash maybe? Did you bolt yours in or use velcro?

Re: LS swap people - Where did you mount the ECU?

Whose harness do you have..
I know that a PSI harness is to short to reach under the seat..that's where I wanted mine
..theres very limited space under dash, but I have mine behind the glove box, above the heater box
Other than that ,it would be under the hood..
On my IH I mounted it under dash on the firewall
Ive heard the BP harness is longer, allowing all the electronics to go under the seat

Thanks for the input. I’m using Holley Terminator X Max.
