I installed a complete 5.7L GM Motor and fuel/spark management system ecm (1228747 not 1227747) from a 89 GMAC G3500 Box Van.
The MAP Sensor tube is plugged into the middle vacuum line in the rear of the throttle body. I will have to check the fuel pressure, currently don't have provisions for that right now, but will this weekend.
I did eliminate all the EGR Controls from this setup. I did leave the EGR Valve bolted up until I can obtain a block off valve. Also I didn't plug in the knock sensor but did leave ESC hooked up to the system. Will any of this effect anything.
