I'm planning on ordering a FFR roadster basic kit this week and had a couple of questions I'd like to get answered first.

1.) My donor car is a 2001 Mustang GT. I've read on the forums that it's easier to buy the pre-made chassis wiring harness Sku: 14503. The description states "The harness also has dedicated power wires if you plan on running Fuel Injected using our available fuel Injection harness." The only harness I can find is the Ford Style EFI harness Sku: 14227 however it states it's for 1989-1993 5.0L Mustang donor.
Questions:
A.) With my donor do I need an EFI harness or is it easy to plug in the stock 4.6L EFI harness?

B.) How does it work with the ford security system?

2.) I live in Maryland. What are the steps to get this kit registered and on the road?

3.) Will I need to get it thru Maryland emissions? If so any tips on how to make sure it passes? Will I need the catalytic converters?

4.) Chip Programmer. I'm guessing that since the FFR is different then the Mustang tweaking the chip would help. If so any recommendations?

I'm fairly mechanically inclined and have built several hotrods in the past. Never built a kit car before but I am going to the FFR build school in May which my answer some of these questions. However any help and/advice would be greatly appreciated.

Thank you,

Jay
