Hello, this will be my first post, and I was wondering if any of you guys have done the 5.0 swap in your s13's. I have been browsing in other forums and I haven't been able to find anything about the wiring. I ask this because it is kind of a deciding factor of whether or not I do this swap mainly because I have seen the engine mounting process and am pretty sure I can accomplish that part of the swap but I have no idea of how hard the wiring is to do or if I will need a completely different harness. This may be a stupid question but I would appreciate it if any of you who have done the swap could give me some tips on how to do it.
Thanks
