The T bucket is a basic 8 circut harness with 1 accessory and it was supposto be designed along with the NTBA's help ( National T Bucket Allience ) but they made 1 big oopsie, they put in GM steering colum connectors when 99% of the time a str8 colum is used, 1 with no internal wiring. I'v heard a couple complaints about this, having to bypass the connectors.
