Haha sorry for all the posts.

I've got my engine and trans all wired up with PSI harness.

Can anyone let me know what else I may need to wire with the factory truck harness?

I have the wires for the coolant temp and oil pressure wired but that's it. There's still a lot of wires to sort through. But I'd imagine I will have to hook up a power and ground back up for the lights and other things to function?

Thanks so much.
