hay guys just wondering if you could use the front speaker live and negaive for the live and negative power source for the fuel cut defencer or is it not a ignition live and negative? coz had my last fuel cut defencer scotch locked in to the ecu live and negative and it wasnt a good connection and now the fuel cut defencer doesnt work id rather wire it in to another power source than the ecu's and any sugestions for good fcd as ive had 2 hks fcd's and their abit tempramental!
