Lewis Hashbrown 4 Report post Posted April 16, 2018 Hi, I've bought myself a 4 in 1 gauge I've got everything else working but I don't know where to tap into for the boost/vacuum reading. Has anyone got some advice or any pictures? Would greatly appreciate it! Share this post Link to post Share on other sites
