Installing a painless wiring system

So, still on this topic....

But got to thinking, is there significance in sharing I have removed the OEM cluster and went with Speedhut full setup?

So, IMO, the only real threat that remains is the bulkhead connector, correct? So is it far more feasible to rebuild (or bypass) the bulkhead since this is the only remaining real threat? Or does the cluster and BH just scratch the surface on potential electrical problems with most A Bodies?
