So I got started today on my head swap & timing chain project. (No garage so this is in the hot a$$ parking lot)I always hear to pull the head w/ the intake manifold attached... So i disconnected the only fuel line i saw running to it (actually it broke -love rust- so i'll have to ask you all how to fix that w/out buying an entire fuel line, but thats later). Anyhow, it seems there is a part of the wiring harness that is attached to both the intake manifold components, and the MAF & Ignition components. I dont see any way to disconnect this, am I missing something? Do I unplug it at the MAF & coil (or whatever it is mounted on the driver fender) and pull the head w/ this 4 feet of wire or does it disconnect at the manifold and I'm just not seeing it... Let me know fellas.
Thanks,
Luke

You will need to unplug all the connectors as fish them through the manifold/plenum. It would be alot easier if you remove the upper plenum to gain access to the wiring connectors. Make sure you label the wires and vac. lines. Some will be easy to remember where they go, but a few might leave you scratching your head for awhile. Also, don't forget the bolt in the front of the head that goes into the timing cover and the mysterious intake bolt by the thermostat which uses an allen wrench.
Good luck

Already got the little bolt hiding in the oil. So the whole harness kinda works its way out of there huh? The upper plenum (the part that says EFI on it?) disconnects from the rest of it? And I am correct on only 1 fuel line right?

Leaving the intake manifold intact, disconnect the fuel line at the rear of the fuel filter, remove any vacum hoses that need to be removed off the valve cover, throttle body and any wires to the distributor, coil and the long gray wire that goes from the coil to the intake(simply unplug this)
I always unplug from the ECU behind the right kickpanel in the cab. Pull the grommet off the firewall and fish the harness through the hole. It is a lot easier and you don't have to seperate the plenum. Disconnect the throttle cable and the assorted plugs to the reverse switch, 4wd indicator, starter, and oil pressure sender. Don't forget the support rod on the intake at the passenger motor mount.
Pretty much all there is. I like to keep it all together as much as possible/less work.
Pull head and reverse procedure to install.
