I'm still working on a 3.4 swap. I'm trying to use as much of the F-body stuff as possible including DIS and whatnot. I had a custom harness made last year by Phonedawgz. I'm not sure I knew exactly what I was getting myself into when I had him make it, but he supplied me with this plug. I don't see a matching one on my Fiero so I'm assuming I'm going to have to make something work here. The tag gives me an idea where it goes but I don't know exactly. I do want to keep the stock Fiero gauges. Any help would be appreciated. Thanks.
