You have several decisions to make that will drive the integration design. Typically grounding is pretty simple and you should be able to ground to chassis. The link doesn't show electrical details needed to make a definitive statement - the ultimate integration design and components you need to safely integrate depend on the current draw for the setup. If the current draw is significant, you may need a relay to integrate the circuit into the 'battery saver' portion of car wiring.
- Do you want to tie in the 'glow lites' with any existing car feature (e.g. headlights or parking lights). If you do, then you'd tap in to the appropriate circuit for the control - but that might require you to wire in a relay, depending on the current draw. Review the electrical spec sheet carefully; rule of thumb I'd follow is to use a relay for anything more than 5 amps of draw - a very conservative approach.
- If you want to go totally independent, look at the various power distribution/fuse boxes under the hood - there are typically a couple of open accessory positions you should be able to wire in.
- Wiring into the fuse box can be a PIA, but it's the safest/cleanest approach. In any case, make sure you wire in a fuse of appropriate capacity. I'd also be careful on the total draw - again, the reason I pose that is due to lack of electrical spec sheet on Amazon. The deal here would be to pick an unused slot, get the appropriate fuse/holder and integrate.
- If you have doubts on your circuit design, wiring skills and knowledge, educate yourself on the car's wiring and its limitations, or spend the $$$ for someone who has the know-how. If you mess up, you can grenade the 12 V charging circuit, which could be a major pain in the $$$$.
- The 12V circuit design on the FFH is not the 'old school' belt-driven alternator and simple controls; MGs provide the high-volt current, and the 12 volt gets charged from the traction battery through a dedicated inverter circuit. While this is a pretty versatile design, it has its quirks - which are also present in the body control modules that manage the various circuits. Not trying to scare you, but you need to know what you are doing. Jamming in a wire to the 12V in the trunk is likely to create problems - things like the 12V going flat under mysterious circumstances.
