Question:

Hello, I was wondering if I can use these as a plug in play, for my 1990 NA, I recently changed my Injectors for the late style Injectors kit but I think I wired it wrong and I don't want to deal with the headache of my shitty wiring skills! - Julian

Answer:

This will ONLY work with Wiring Specialties EFI harnesses.

Question:

Can I use this harness to upgrade from old injectors to new injectors or do I need to buy the old injector harness and the pigtails separately? - Patrick

Answer:

Hi Patrick, you can use this harness if you already have a Wiring Specialties EFI harness. It will not work with the OEM harness as the injector connectors are hardwired in
