i did some research and didnt find a whole lot of info. msd makes a direct plug in adapter for the TFI on mustangs... will that plug into my truck? is it worth the extra money to put a multi-spark ignition on my truck? basically i plan on doing a 4.0 or maybe ill plug the 5.0 in there if i feel like doing the extra work but i don't have the space nor the time at the moment. I'm asking cuz i want the info not to be told its useless
