Go to this link to see the V3 assembly kit http;//www.glensgarage.com/catalog/megasquirt-components-p-64.html I am doing a complete engine internal rebuild all parts that are going on my car are on my profile but just dont want to buy the wrong thing. I know you have to assemble this one but making sure if this is the item that is going to replace my SAFC2 and I do not have any Megasquirt devices but just wanting to know if all the parts will be there to build it. THanks dsm tuners community and by the way thank you moderators on all the forum sites that I go to I have never seen as much support from the mods here than I have ever seen on a site ever! so thank you as well!
