Basically what the title says. i don't want to hook everything up yet until i know the engine is going to be ok. there's so many wires and vacuum ports and i don't know what a few of them are for. The motor's an LG4 with a CC q-jet. Should i plug the unused vacuum ports for now? Thanks for any help

 

Yes, plug all the unused vacuum ports until you are in a position to hook them up. The last thing you want is a vacuum leak when trying to establish whether or not your engine is running correctly. Keep the PCV valve connected though.

 

....and when you are ready to connect everything, here is where it all goes.
