Some will argue that relays are needed in all instances but I feel it could be an option. Another option is a kit to mount the battery in the trunk with rear mounted "kill switch" that meets NHRA requirements.
If you convert to different (non-stock) type bulkhead and connectors then buyers could not piece it together with stock system at common connector points. This means that it's an all or nothing deal and would raise the initial cost to buyer.
