[Ramairnacho]

As some of you know I'm restoring my dad's only 1979 formuka 400 ram air 3 auto with AC. I expect my carb. Back in a few weeks and was reading about fast idle controll. Does a formula auto 1970 with ac require the fast idle. I don't have the original harness anymore got lost or misplaced since my failed attempts as a kid to install rally guages andcwill be have a new harness ordered. So I can not use that as a reference. On Facebook trans am group I read that it started in 71 but 1 have seen 70 with it. Are the ram air 4 only cars only cars with fast idle in 1970. Please advice. And you guys help me and I appreciate all the comments both negative and positive. I will have alot of knowledge about my car when done.
