Evening all, I am new to the site and new to the world of Mini's. My sister has bought a Cooper S 2004 and wants to fit a boost gauge, is this advisable or a big no no. If so could anyone please give me some advice on how to do the job. I am handy with the tool's so i am not scared lolololollol. Many thanks Ross

Instructions vary slightly depending on the specific boost guage and where it is located. Things to look for when purchasing a guage is to make sure it comes
with a wiring harness not just a bunch of loose wires becouse then you are
going to need a wiring diagram to route all pins and find good grounds.
