auto sr20det wiring questions...Bet you dont know...

[wlfnsheepsclothing]

So I have the early yeared sr20det wiring harness and it was originally for an automatic application (trying to put this into a '95 s14). I have all of my wires prepared and ready to go except for two stranger wires. The two wires lead to a third power plug aside from the two normal plugs used in a common swap. The two wires are colored as L/R and L/G. I followed them back to the idle control valve but I do not know if the send information or they are just power wires. Also there is a PCM valve that sits purched next to the ignitor chip, does this control fuel pressure or boost pressure? Last but not least on pin 105 R/W where does that go lol?
