Here's the kit I'm using and pay close attention to the use of a Ford style remote starter solenoid. This keeps the starter wire dead until you energize it at start up. (It's a safety mod!) Use the frame for ground. This mod also allows you to install the required emergency power cut off switch at the rear of the vehicle closer to the battery. Read this...

Don't disagree but 2 things:
1-"Ford" solenoid is fine for a starter, but is not continuous rated. The kit doesn't use it that way, but somebody might try to use one to disconnect all power downstream. There are continuous rated solenoids available if somebody wants to do that.
2-I know there are a lot of people with remote batteries that rely on the frame for ground. I come from the heavy truck industry. They (and heavy equipment too) mostly pull a full size ground from battery to starter. Is it necessary? Maybe not, but starting performance is maximized. I would at least run a same size or 1 size smaller dedicated ground from battery to starter or block in addition to a frame ground. Ground wires are some of the most overlooked wires in automotive.
