You can also give J-TEC Performance a call at 813-546-3524. He can install the ballast resistors in a very clean, OEM fashion. He can also wire up the Cobra MAF for you as well. If necessary, he makes house calls.
By the way, are you running MSD 50 or 72 lb/hr injectors? The 50s do not require ballast resistors, but the 72s do.
Ask for Jay Whitely. He knows his shit.
Peace,
