i swaped out engines in my 87 k5 blazer (tbi) 350. well i had a bit of help, so when i went to start hooking wires back up after i got the motor in, i don't know where some of the wiring goes?

 

which wires??? Every plug is different, and there really aren't that many sensors.

As long as you didn't cut the wires anywhere you'll be able to figure it out. Upload some pics to uploadit.org or photobucket if you get stuck
