Billet Specialties 66935 four port inline heater and air conditioning bulkhead connector.  I never used it, I ended up going with a different type of connector. Condition is as new. Brand new price is somewhere between $70 and $80, I am offering it with no reserve, just a very reasonable starting bid of $45.00, so save yourself a lot of dollars. Will only ship to the United States and will send via US Postal Service standard mail. Good luck and happy bidding!
