EFI to Carb

Here is the deal, I have an 85 bronco that I just put a motor in and I took it out of an 86 bronco for a friend (he told me the 85 was EFI). Any way the 85 is not. I feel that wiring the bronco to EFI might be over my head, or take me a long time. So what would I need to convert to a carb. I know intake and carb, will I need to change the distributor, or can I use the stock. The stock has about 8 wires coming out of it. Which ones should I use. I will need to run an electric fuel pump. But I have the intake, an older street dominator intake from holly, will it fit this 86 motor. Should I try to make the EFI work before I convert. If so I need some pointers in getting started. I have been told only about 7 or 8 wires are needed to make the motor run but I have no clue which ones. And I have been told it is almost impossable to do. All info on this subject will be helpful.

The Holley intake and carb will bolt right up to the 85 or 86. Just use the 85 distributor and if you want to run a mechanical fuel pump, put the 85 timing cover (along with the fuel pump eccentric from the 85 motor on to the 86 motor.

IIRC, evrything after 82 had feedback carbs and TFI ignition. I would recommend an older (around 78) DSII system, or a Perfomance Distributors unit.

If you have both complete engines, just swap the parts listed in my previous post and you should be fine, since both vehicles use the TFI.
