I just purchased a complete running engine from a 2003 suburban with a 5.3. It doesn't have a throttle body intake but it does have a 4011 ecm. I want to use the factory ECM and going to go with E85. My plan was to use 105lb high impedence injectors but am being told I cannot modify the wiring harness to work with a throttle cable intake. Is there anyway to modify the factory wiring harness. Also, I am assuming I can just delete the throttle sensors from the ECM so I can use a throttle cable. Am I correct or way off?

Thanks.
