So I just swapped out my motor 5.3 ff.

So can anyone tell me where I can get the schematics that I can use to help me track down the problem. Something that shows me all the connecting points for grounds and may the vehicles sensors. I think that will help, thanks in advance for any help you all can give me.

Thread moved from the EV section, but you didn't say what you're working on so I'm not sure if this is the correct place for it now. Consider adding some vehicle info to your signature so it's always there. Year, make, model, engine, etc.

You can find wiring diagrams at www.charm.li which also shows sensor and ground locations.

FWIW We need to be a little cautious when responding with Gen-specific info, as we don't know on what vehicle the OP is working.
