i suppose this could be the case if originally you got a harness for an automatic trying to use it for a manual and you go through hell trying to figure out why the fuck it won't idle and then suddenly realize why...

but the deal heavythrottle's got going on isn't too bad for novice or inexperienced electricians.

personally i'm most likely going to be going with standalone, either sds or electromotive tec 3. and i'm not even going to fuck with doing the swap myself, i won't have time.
