hello all. i am putting a 351 engine from a f250 into my f150, unfortunatly i only had the frame, motor and transfer case. So I do not have the computer to install with it. I have found there are like 12 different possible computers from parts stores and i need a number from the cab which i do not have. i was wondering if anyone knows another way to find out which computer to use. I also was wondering if plugging in an after market module which replaces the chip in the computer would work. thanks
