I have built jeeps and truck all my life and i am a complete newb on these cars.First off please forgive me on asking about a subject that has been beat to death from what i have seen allover the internet. Long story short, i am helping my stepdaughter who has a s13 sohc and have transplanted a dohc out of a s14. I do not have a ecu for the s14 dohc, but i do have one for a s13 dohc. i know now this will not work. I have a harness for the s14, could i just get a s14 ecu? Again thank you in advance
