Are the harnesses from an '86 and 88' NA the same? Like are the injector connectors same or different?

 

No.

 

If you are looking to replace broken connectors I used this link at Summit Racing to get new connectors for an 86 NA we just finished, even had four to spare.

Hope that link copied ok, first time I tried this.
