@eyeteeth - I get the impression that vacuum line isn't attached to anything ... just the carb and loose at the other end. If so, plug it. Or, remove it and cap the carb fitting.
If my impression is correct, it's creating a vacuum leak that will really mess with your engine performance.
As for vacuum hose routing, check with your state agencies. When Alaska initiated it's motor vehicle emissions testing program, the state legislature required the program provide detailed relevant maintenance diagrams and text to owners and maintenance shops.
Your state (Michigan) may have a similar resource available.
I corrected the horrendous vacuum hose mess left by a previous owner when I overhauled my 1980 Bronco, using the free information provided by the state. The information they provided was specific to the year, make, model, engine, and VIN. It eliminated the head-scratching most maintenance manuals cause when it comes to vacuum hoses.
As for LED replacements for OEM incandescent bulbs, I have concerns. Incandescent bulbs emit omni-directional light while LEDs tend to be unidirectional. So the LED replacements don't always work well in some fixtures. IIRC, the standard for various motor vehicle bulbs require a specific output, which corresponding LED replacements have to meet. However, is the LED 'aiming' its light output in the right direction?
For this reason, I prefer to replace the fixture rather than just the bulb. However, this does cost more and it may be difficult to find a suitable replacement for the OEM fixture.
