1991 5.0 HO Miata swap
Hello guys I'm new to this site. I'm building a 5.0 swapped Mazda Miata. I purchased a 1991 Thunderbird with a 5.0 HO and auto trans. I have stripped the drivetrain, ECU, wiring harness etc. My question is can I use the wiring harness and ECU if I'm using a T5 manual trans. I'm not sure if the harness can be modified into a "hotrod" harness or if I need to go with a different engine management system like Holley or Haltec etc. Thank you in advance!
