I was trying to instal a fuel cut switch, thought the instructions were pretty simple.

problem is I think I got confused which plugs on the switch were which (groud/power/load)

if I pluged them in the wrong order could I have hurt anything?

I took off the switch and put it back the way it started, but now my car wont start...

 

Yes, you could fry some wiring, or smoke a fuse. I'd check your MOTOR fuse to start.

 

It's the ENGINE fuse.

 

Close enough!

 

I most definitely blew the engine fuse, thanks for eliminating the trouble shooting for me, and anyone else that might make this mistake later.
