Note: This is an ongoing post, which will be receiving updates as I gather materials (pictures, working designs, etc) to show off as much as possible.
Picture the following:
You have a fairly modern vehicle, and while it may or may not have anything fancy, it has everything you need to get you by everyday. But, lets say, you want to add a few things to your vehicle without breaking out the credit card or simply prefer to do it yourself while saving a few dollars.
You install an alarm w/ or w/o remote start and find that simple enough to work with and decide to add a few more convenience installs to your trusty vehicle. So you decide to make a few enhancements here and there but you want to keep your vehicle looking stock (no modifications to your dash that leave a part exposed and different from how your vehicle looks to any other from the same brand and model).
OK, lets say your car had the option to add heated seats. And you can still add it if you buy the parts, so lets go with that. I will use my vehicle to demonstrate this work process.
