So I went to the hardware supply store today and came up with a solution that is a little more expensive, but will ensure the module is removable when you choose to do so. However, it does still involve cutting one wire but would come with bullet connectors to easily reverse the installation back to stock if you ever chose to do so.
It's very similar to what I sold previously, with the exception of one connector being different, now the ground wire will use a quick splice connector with a male bullet connector.
One module kit will consist of the following:
I will post final pictures once I have another module to wire everything up with. Connectors will have heat shrink on them to keep them insulated on the module side.
