550cc injector Install help - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

I bought some Sard Denso 550cc injectors part no. 19550-2460. I did some research and they seem to be the primary injectors from an FD S6 RX7 (1992-1995) model. I want to install them on my Redtop SR20DET but the connectors are different. I was told to "de-pin" the stock plugs but I'm not sure on how to properly "de-pin" them or if that's what I even need to do so the 550s could plug in fine. I searched around but couldn't find anything on it. Closest one I found was on here for the secondary 850cc RX7 injector install on an SR. Could anyone please help me on how to "de-pin" the stock plugs/installing the 550cc injectors? Thanks for all your help. Pics of the injectors are below.

order the connectors. The clips are different from the sr20 and the 550cc (aftermarket denso). I went 550cc to 850cc and both used the same injector clips from denso.
