im trying to check wiring for cross talk before putting in top harness /top end
I had more than a few bad injectors looking at the bottom harness that leads to the engine fuse box there is a black and a grey bulk connector that connects to the top harness half .....no cross talk that i can gather from pins but I have the red/grey striped wire showing a buzz or continuity to the rest of the engine block! also with the orange wire and red ltblu wire ..... is it supposed to do that ?? the o2 sensors are not connected the entire top harness is out
if I connect the negative battery terminal to the positive battery lead there is no continuity only the engine block and various close ferrous parts
ive modified the pic
lattest test was to disconnected the pcm harness (nice 10mm din there passenger foot jamm area) and put the vehicle in reverse to take it out of park still with continuity from the red grey to orange and red lt blu and the engine block no battery in truck
