4 & 5 pin ECUs

Thanks gents. Just went out to confirm, and I do have the factory style connectors with the nubs. I noticed it's possible to switch left and right, but it can't go together upside down.

I'm going to just start my own thread about my issue so I can stop stealing other guys' threads - I've been lurking in the ignition forum for a few days trying to work it out on my own, but no luck.
