About extending my box into the cabin

Now apparently all I am going to need is a standard serial extension which I have ordered so the next project is going to start next week when I get it!

Will be testing first to see if the box is happy with using that length of cable as I'm worried it might lose some voltage with the cable being so long but I will have to see!

I am going to locate it inside the centre console armrest hidden out of the way, and this could be used as another security aspect as when the car is left Parked up, it can be removed and even with the key it could not be started!

I'll keep things posted but should be in by next week
