I would have to buy the pig tail for it right and splice it up?

the point with using STI injectors is that plug is identical other than the rib shown on the side of the plug. If you grind that rib down, the stock SR20 wiring harness plugs in. That's one of the main reasons why they are so commonly used in SRs.

I had STI 550cc side feeds on my SR up until this last weekend, and they were plugged into the stock injector plugs.

Secondly, Enthalpy and other tuners will tell you that the spray pattern and ability to tune STI injectors are far better than the old fatty MSD top feeds (less idle richness problems and more).

For practical purposes, the STI top feed 550s are also better than side feeds for several reasons, which is why big setups always run top feeds.

ill would be running this on a ka-t setup, is it the same plug and play wire harness besides the rib?

That I am not sure about, as my 240SX already had an SR20 swap when I bought it. My guess is that they are the same, but I can't personally say for sure.

I probably could take a close up photo of the injector plug if you can take a look at your harness.
