Where you guys placing the ECU on 65 Cudas/A bodies?

I dont have a picture, but I mounted mine inside the firewall. cut the wires, ran them through a grommet, & soldered them. I mainly did it because I didn't want to see it (pre ECU car). I was worried that if I needed to troubleshoot, it would be a PITA, but since I never had a problem, that was a non-issue. BUT, that was an original MP conversion kit from the days when you could trust stuff to work and last.
