Holley EfI with out Tcc plug

[707v6buickman]

I have a holley efi harness but when getting it built I must of said something wrong because my harness doesn't have the transmission lock up plug. is this gonna effect my car for normal driving

what Holley did you get? and what transmission do you have? and what harness?
It would be best to have it. depending on a few things it's not hard to add. I just changed my car from non locking to locking. I have not got it on the road but Im confident it will work.
