Need Information Please!!!!!!!
Anybody know what this plug is for?
The next 2 pics are vaccum lines. My truck has a small mis and I'm thinking it's a vaccum leak. I would like to get things back to where they go. I'm not sure.
The last one is another plug coming from the firewall. Red/green stripe wire,black and red wires.
Thanks for any help! LEE.

The first pic looks like the harness for the distributor.
The vacuum nipples on the thermostat housing are not vacuum sources-they're not a cause of a vacuum leak.
The vacuum hoses with screws in them could be a problem. If you're not using that tree, pull it out and install a plug
Fortification has wiring diagrams that will show you what the other plugs go to.
If it runs as it is, perhaps it's been converted back to a points style ignition. That'd explain those unused wires.

Thanks for the help. Not sure if points has been changed. It's a very nice truck but has a lot of little things that drives me nuts. I think I have a bad harmonic balancer. The engine vibrates along with the balancer wobble. I have 2 different exhaust manifolds. I'm thinking about headers. Any suggestions for a stock truck. Doesn't seam like enough room for long tube headers. Just figured out that I have a bad temp sensor. That should be easy fix. Any help on headers will be great. Thanks for the help. LEE
