Power Inverter

Does anyone have a really good write up for a power inverter install that looks OEM? You can buy the OEM Toyota AC plug, so there must be someone out there who has wired it up to look and function like OEM with a better than OEM inverter. I really want to hook one up, but want it to look like truck came with it. I've searched through a bunch of forums and no one has really done a great job or put together a write up that makes sense about it...

 

I saw one on here, let me see if I can find it.

 

Here it is:

That was the best write up I could find, but I'm he never explains the wiring to the solenoid or why he used that over a relay? Not a fan of the outlets either... I want to find a way to use toyotas outlet, but I'd have to figure out what wires are what...
