Installing the FM ECU required several modifications to my Sebring System. I ended up removing the MSD unit, Air Meter, and Sebring air filter.

I removed all Sebring specific vacuum lines. I then added a single new vacuum line which originated from a "T" spliced into the stock fuel regulator vacuum line. This line is routed along the firewall over to the FM ECU MAP Sensor.

I also replaced the stock injectors with higher flowing 370cc units. This mod allowed me to remove the AFPR and High Pressure Fuel gauge.

The new 370cc injectors have a different electrical connector from the stock injectors. This necessitated replacing the standard injector connectors with new ones. This required cutting the old connectors off the existing injector wiring and soldering the new ones in place. If you are handy with soldering iron this is an easily modification. Dealer Alternative supplied the connectors with the new injectors.
