dave205 19 Posted October 2, 2013 I have a v6 in my 306 as most of you probably know already because of the cooling issues. Another issue is i cabt get the speedo to work, does anyone know how to do it? I thought i'd wired it up right but obviously not! :/ Share this post Link to post Share on other sites
welshpug 1,737 Posted October 2, 2013 use the three wire original 306 one, add a 12v switched and earth, signals to ecu and speedo, signal and earth already there. Share this post Link to post Share on other sites
dave205 19 Posted October 2, 2013 I think i left that on the gearbox when i sold it unfortunately. The 406 2 wire one goes to box of tricks in the dash doesbt it? Share this post Link to post Share on other sites
welshpug 1,737 Posted October 2, 2013 yup, but the 306 doesn't use a box of tricks, hence needing to add a 12v+ and use the 306 sender. Share this post Link to post Share on other sites
dave205 19 Posted October 3, 2013 Will the 306 sender fit in the 406 gearbox though? Share this post Link to post Share on other sites
dave205 19 Posted October 3, 2013 Well the reason i ask is the 406 is an ML gearbox not a be one Share this post Link to post Share on other sites
