2 gray plugs on rb25det

[sviellvoicae]

Hey guys I just completed my rb25det swap and everything runs great but im still a little confused about these two gray plugs. They are 8 pin plugs I believe and there are two females and one male. The male fits both females but I have no idea wich one to plug in. Thanks

Find a decent wiring diagram of the engine harness and match up wire colors... say one connector has a yellow wire with a black stripe, a black wire, a white wire, and a red wire - odds are pretty good it'll be the only connector with that wire color combination.

ALSO, wire colors in cars like these usually continue from one connector through another. So if the wire colors of the one male match one of the females', odds are in your favor that they go together. The other connector you can determine what it is by wire colors as well on a diagram such as the following:

One is for the injector harness.
Like SpeedEast suggested, check the wire colours that you are connecting. One side of the plug should match the other. I don't remember where the other plug goes to.
