when concerning going backwords in technology what is needed when going from EFI to carb?

The wiring is what I'm mostly concerned about. I've heard it's really simple but I'd just like to know what goes where...

 

If you use and msd box it is quite simple! You will need a Carb,intake,distributor,fuel pump and msd box etc!

 

really simple, need fuel pressure regulator, and the only wires you need to keep are, oil press, temp sensor. If you go to a msd ignition and dist, then it's even easier.

 

ok well my brother is hookin me up with his 81 grand marquis that has a rebuilt 302 with a 2barrel carb. new rad, rebuilt tranny and etc. I have an MSD 6a I can use and the doner car is an 88coupe that was originally a 4cyl. The 5L wiring harness has been put in but not installed as it were. dash is off and wires are everywhere.

I'm currently ripping apart my 87 hatch 4cyl and will be using the hardware to reinstall everything.

 

As stated above very simple Battery wires, Alt wires, start wires, ok now im running out lol
