pleasure any time . one thing to remember not sure if it covered in the book is use a master fuse (fusible link) in the supply 12v cable to the fuse panel . any damage caused by a major fault will come from the battery, fuse that with a replaceable bolt in fuse example see below 40amp or 50amp should do, larger if running fuel pump, elec windows and thermo fan then fuse at 80amp
