I'm gathering parts for a mass air EFI swap to my 289 (stock cam if possible) & T5, to perform late spring or early summer. I just purchased a 91 mustang upper and lower intake complete w/ fuel rails w/ the mustang stock injectors & a 1989 - 1993 mustang 5 0 mass air A9L computer & harness, stock throttle body, and injector wiring harness

I still need to get a stock mass air sensor, distributor (will swap gears), coil, O2 sensors (o2 harness?) and fuel lines and pump setup ect.

My new questions are:

My main harness and computer came in and everything looks well. I cleaned it up and started marking connectors. I know where all will go except what to do with:

1. Barometric Pressure Sensor (is this needed, can it be bypassed?)
2. and ERG connectors. I dont want to install an EGR system on my 65 289, how can I baypass this?

If anyone has any suggestions where I'd be better off finding these answers, please post. Im doingmost of my research on fordfuelinjection.com Thanks!

Only mods I plan are headers till I get comfortable w/ EFI

A MAP/Baro sensor is a must have sensor. The computer goes into limp mode without it.
