i have a 84 gslse and what i can remove and not remove out of the stock wiring harness to put a halteck f10? thanks

 

welcome to my world. :ugh: its tough and there is no specific list its all trial and error here bro or to my knowledge. if somthing doesn't work when you done the you need to plug it in. you will proly end up disconnecting a hand full of things to put the haltech in jsut try and kep it to a min.
