Whew? From memory, there should be a small plug the same size as the hardware in the WP kit, which is located on the top of the actual cylinder head, above the upper spark plug on either the right or left bank. Some models have this plug on the bottom of the head, and others are located on the water jacket plate, on the bottom, which is the plate in between the two heads on a V-6 engine. Once you have located the plug, remove it and verify that you have pulled a plug from the water cooling system. The fitting is to be screwed in there, and this measure the actual water pressure contained in the block. If you have purchased an independent gauge, such as Teleflex, VDO, Beede or Faria, you may not have hardware to complete the installation and you will have to visit you local handy man automotive store, or NAPA. Chain Automotive stores seldom have the couplings and hardware with ferules to complete the installation. Though if it is the main source store for your local mechanics, they often will have a parets bin for bronze accessories. Hope this helps!BCB
