What is this stuff?

[krazy skwerel]

OK I have this plug on my fuel injector harness that I have no idea where it connects or if it even needs to be connected. One of the wires going into it is the thick blue w/red wire. Also what is this sensor for and where do the wires for it come from.I appologize for being dumb, but I am lost on this stuff.



Also where do I hook the end of this hose to or can I just cap it off?

Thanks again for the help.

Well if you want your coilpacks to fire you better plug er in, it goes to the coilpack subharness coming out the back from under the center cover.

The hose would have gone to the pipe feeding into the throttlebody.

The plug is for the sub-harness for the coil packs.

The hose needs to connect to the intake coming to the throttle body. That feeds the air for the idle control system.

I never knew that hose existed for the IACV. Especially since its long and stetches across the engine. Is that stock because I don't remember that when I did a ca swap.

[themadscientist]

It should not pass in front of the engine, it was probably jammed over there for shipping. There is a port on the stock pipe that crosses over from the intercooler that it goes to.

ok so I just need to connect it to my cold pipe then. Cool cool what about that sensor I circled? It has the wires cut and I don't know what it connects to. Trying to find it in the wiring diagram but so far no luck. Thanks again for all the help.

The sensor is the A/C idle valve. It 'ups the idle' when the A/C is turned on.

Also the FICD sensor, also known as USELESSSSSSS

Excellent I'll just cap off the wires then. Woo hoo.

Well, you have two sets of cut wires there, are they the same colors? If so I would reconnect them. It can't hurt.

[krazy skwerel]

They are not the same color. Also if that sensor is for A/C then I dont need it anyways since I have no components of the a/c system still on the car. The other two wires are blue w/red though they are smaller than the big blue and red wire.

That makes sense. Thanks for clearing that up. Im still a ca newbie.
