Hello - just did an engine swap but FORGET how some of the connections go.
Firstly - please see my question on video attached.

• Where does the BLUE negative battery cable tie down to? The engine?
• How does the OIL separator hook up? IE Hoses?
• There are 3 hose connections on the intake I need guidance on.

Please see my video. IF you can make a video of you 240 and explain the connections that would be a HUGE HELP

Here is a link to my video... https://drive.google.com/open?id=1-V...gcWSbOX0WEmLmS

Thanks!!!!

 

the battery negative cable goes to the chassis near the battery platform, should be a flat slot with a big bolt hole.

the vacuum nipples on the intake manifold connect to various things that need vacuum, including...

1. brake booster (larger diameter than the others)
2. hose through the firewall for the ventilation controls
3. charcoal vapor canister
4. ignition controller on 240 models up to 1988 that use Chrysler ignition (not applicable to your 91)
5. .... anything else that uses vacuum, that I'm not remembering offhand
