    Put it where the sender for the oil pressure warning light is. Most of those gauge kits come with some sort of adaptor so you can plug the new sender into that hold, and also plug the original sender into the new adaptor so your old light still works too.

                i'd give them 50-100kms to get fully adjusted.
