Hey guys. Couple questions and thanks to anyone who can help
im not sure weather or not to remove the ecm completly or unplug all sensors etc and run the harness through the fender well.
Will my new efi system control the engine still with original ecm still plugged in just with no sensors hooked up?
and if i were to completely remove the ecm, do i need to run new battery, starter leads? And what would be your suggestion on weather to keep or remove. Done this a few times on carb ran vehicles. When it comes to an ecm ran car im super confused. Going to be starting the project tonight so any help is appreciated.
