Ford Mustang 1996-1998 MS3Pro PNP Plug and Play
The #1 PNP ECU for SN95 Ford Mustangs! MS3Pro PNP ECU provides complete control of fuel, spark and MUCH more including the factory dash!www.diyautotune.com
I have this same setup on my Foxbody.
Literally plug into the stock ECU connector, and run a vac line for the MAP sensor on the ECU. If oyu do a single wide-band you can make a adapter harness and just plug it into the stock O2 harness. I'm running dual wide-bands so I made a separate harness to run back to the ECU. Comes with a canned tune to get you up and running.
Decent forum and FB group for support. When it comes to tuning you are own you own a bit, but there are folks that know what they are doing that can set up a tune for you.
Holley is a bit more user-friendly and they offer great support. You will need to change out the entire harness however.
