I had Perplexity and ChatGPT generate and critique each other's analysis of your diagram. Here's what they spit out:
Hey shtbrwn86,
Good job on mocking up a diagram for us to look at. Alright, let's dive into this wiring diagram and see what's going on. The goal here is to get both the left and right air vents in your Land Cruiser to play nice with a single switch, which is a pretty nifty customization.Looking at the diagram, you've got two separate circuits for the left and right vents, each with its own switch. The proposed setup is to connect these circuits together so that one switch controls both vents simultaneously.Here's the breakdown:
- The red wire is your power source, coming from a 15-amp fuse. It's split to provide power to both switches.
- The orange and green wires are the outputs from each switch, heading to the respective vents.
- The blue wires are for the illumination of the switches, and they're tied into the vehicle's illumination circuit (ILLUM + and ILLUM -).
- The black wires are the grounds for the switches.
Now, if you flip the switch to the "CLOSE" position, both the green and orange wires should be energized, causing both vents to close. Conversely, when the switch is in the "OPEN" position, neither vent should receive power, and they should both open.
Potential Issues:
- Current Load: Make sure the new switch can handle the current required to operate both vents. If each vent draws a lot of power, you might need a switch that can handle the combined current without overheating.
- Switch Rating: The switch should be rated for at least 15 amps since that's the rating of the fuse in the circuit.
- Illumination: The diagram shows the illumination for the switches tied together. Ensure that the illumination voltage and current are within the specifications for a single switch's illumination circuit.
Improvements:
- Relay Use: If the vents draw significant current, consider using a relay. This would allow you to use a lower-rated switch, which might be easier to find and could potentially last longer.
- Fuse Rating: Double-check the fuse rating. If the combined current draw of both vents is close to 15 amps, you might want to go with a slightly higher-rated fuse to prevent nuisance blowing. But be careful not to exceed the wiring's current capacity.
- Wiring Check: Ensure all connections are secure and that the wire gauge is appropriate for the current it will carry.
- Switch Quality: Invest in a high-quality switch that can withstand the rigors of off-road use, which I'm guessing your Land Cruiser sees from time to time.
- Labeling: Label the new switch clearly, so anyone else who hops into the driver's seat won't be left scratching their head.
Overall, the diagram looks like it should achieve your goal of controlling both vents with a single switch. Just make sure to address the potential issues, and you should be all set for a smoother and more streamlined vent control experience. Happy modding!
