360 Magnum with stock EFI engine codes

You have codes because they are not hooked up . So what are you asking ?
If the computer does not get a signal it will have codes forever until (1), you have the items that are missing connected, (2), you have the computer reprogrammed.
My post said I was asking for possible fixes. I’m well aware of why the codes are there. I’m also aware there are plenty of smart people on here that have done similar swaps and have probably come up with clever solutions. What I’m looking for is people to say “this is how I took care of this code”.
