Painless wiring I have a 1979 camaro with a ls6 and painless wiring.
painless has indicated the use of 0411 ecm and Delco afs75 o2 sensors and other specific parts.
I am unclear if afs75 are grounded at the body or through the ecm? I am using an ecm from a 99 body not 0411. My O2 sensors are not working, would anyone know if that's because of the ecm or the o2's?
