Di/ pricol... I Pm you that... Ill check to see if theres a module thats bringing power to them, as you know my boost gauge quit now.. Josh still does have my IDM im going to have to try to swing it there sometime..
I haven't had time to do much looking but you should check out their site, try to find some schematics, let me know what you find. My isspro's have a driver module that run them. let me know.
