Some one had posted what's involved in swapping an 87 camaro from efi to carb. I have done this and everything works great .However his Comment was now that it's all complete remove your computer as you wont need it if this is correct I can remove mine and all wiring to free up the engine bay of wires...

 

You might want to unplug the computer and see if it causes issues before you rip out a bunch of wires.

 

It's been a long time, however, I don't think it's as simple as a straight removal. You'll want to map every wire and verify that none go to a dummy light or something that's going to pop on when it's unplugged. Otherwise yeah, no problems.
