Very true. make darn sure you have good grounds.
When building up something like this or even more radical I tend to run dedicated grounds. Every component is grounded back the the Neg. post in some way.
Especially in a bracket car with all that electronic Bravo Sierra. I use 2 Terminals for power distribution or share one. Everything gets a dedicated ground. It just works better. Still ground strap the chassis but do not use it a common.
