Great looking work,the only concerns we would consider is that too many grounds at the same location as with too many positives at the same location can trigger interferences if one or more accessories have an issue.This can cause a electrical nightmare to find a problem.We eliminate this issue by having separate systems for ignition,fuel and cooling as well as any computer circuts.Sometimes moving grounds or positives for these main power accessories a matter of 6" to 12" apart can cause any interference or backfeeds to diminish and not create other issues.
