Hi Im David, thanks for visiting the site, Under the hood in the fuse block, there are large 30-60amp fuses. Hook up your amp meter to the battery, let is stand for about 10-15mins, this will let all the computers go to sleep. If your draw is above 100mAMPs, then remove each one of these fuses to see if the draw goes down.
Make sure there are no aftermarket items hooked in to the eletrical system.
Let me know if this lowers the draw.
just checking in to see how its going
