Long story short I bought a car without an engine harness. Found a matching harness and got it all routed and connected(or so I'm 99% sure)

When I connect the battery the door chimes come on and the courtesy lights come on with the door open, but when I turn the key on I have no power to anything. Nothing on the cluster, no radio, no windows, nothing.

Tried swapping mfi fuse, ignition switch and still nothing. What else can I check?

Have you checked the the pink 30 or 40 fusible links?

Yes in the engine bay fuse box?

Have you actually tested for 12v at the ign switch?

Check for the constant 12v, and trace back from there if it doesn't have any power there.

It SHOULD be part of the body harness, but I don't recall on a 2g. Believe it'll go directly to the fuse box at the aforementioned fuses
