which series rb am I getting ?McKinney Motorsports wiring question

[GIJOE69]

I just ordered a RB25DET from a 96 skyline which series would that fall in 1 or 2? and also when I do get the McKinney Motorsports wiring all the gauges will be working and read accurate except Tachometer? but the speedometer will be reading fine from S13 KA cluster? and water temp and all them gauges

[Nameless EJ6]

Should have done all the research before you started this. It's pointless to jump into this without any real knowledge of what you have or what you're getting.

96 is series 2. If you searched for this, you would find that info.
