Installed FMIC, but I think I messed something up...help!

[Rice Over Wheat]

Ok, I spent 13 hours just mounting my fmic thanks to having to use a drill and a dremel to do my cutting. So I put everything back together, or so I thought, but now I have an extra plug disconnected. I have no idea what this plug is for. Here's a couple pics. It's not the fog because those are lower and zip tied.

Look familiar to anyone?




EDIT: Removed my parking lamp question. Found a thread on it.

Is the plug for your coolant overflow bottle? As far as the turn signal, check the rear bulb. It may be blown on the side that is flashing fast.

When I removed the coolant bottle's bracket during the install, I noticed a couple plugs under it. Neither was connected to anything though...one had a twin nipple, like it's an atmosphere sensor or something? And the other I didn't know what it was. So the coolant bottle is supposed to be have a plug connected to it?

The plug in that picture runs off of that large bundle of wires that lies behind the passenger side vertical frame bar next to the radiator - the one you have to cut for short-route kits. When I unbolted the coolant bottle, there were two wires with plastic ends bolted to the bottom of the housing bracket. They weren't connect to this plug though. (i think)

it looks to be the harness that connects to the low level sensor on the coolant overflow

looks like the bcs plug

 

[turbodsm18]

looks like the bcs plug

I agree

 

[Rice Over Wheat]

What is the bcs plug? I did a search and no results. Same thing as the low level sensor on the coolant bottle that the other guy mentioned?

The car drives perfectly fine despite it being disconnected.

What are the wire colors? I can tell you what it is once I know that.

Its the plug that connects to the stock Boost Control Solenoid normally underneith the intake that has the Y shaped vacuum hose coming off it going to the turbo boost source nipple and the wastegate actuator.

 

[grnchevyz]

If it's the BCS plug you will throw a code (Check Engine Light) Do you have one?

Hm...considering I have my mbc disco'd until I get my 650s in and am just running off the 17psi actuator, I guess it's possible I wouldn't notice if its disconnected. I will look into this tomorrow morning.

I always have one. P0505 Idle Control System Malfunction. I haven't done anything about it because my car drives perfectly fine. Maybe there is a new code...I'll check tomorow.

Thanks guys...will update later.

I agree it looks like the lower harness for the coolant bottle. Mine had the exact same thing, I just tucked it away and called it good. Check to see if it throws a code. If its the BCS it will throw code calling it a wastegate solinoid valve. I cant remember the exact code off the top of my head, but if you want it i can look it up.

I don't think it's from the coolant bottle...I think those are connected fine.

Here's a close up pic from under the car of both connection wires that were bolted to the coolant bottle's brace. Those two are near my finger tips, one has two nipples off of it. The one I can't figure out is the one that is by the palm of my hand. I can't see anything underneathe the car that it can connect to.

Also, I tried to trace the mbc lines, one goes to turbo and the other goes to the actuator with the mbc in between. I can't find the BCS...where is it?

 

[Boosted98gsx]

2 nipples = BCS

 

[Rice Over Wheat]

So the plug on the left in that pic is the BCS? Then are those 2 nipples supposed to be connected to something?

That still leaves a mystery plug on the bottom of the pic.

 

[spyderturbo007]

I can't find the BCS...where is it?

In your hand.

 

[Rice Over Wheat]

In your hand.

Oh shit, then my lines really are disconnected. Can someone please tell me which lines are connected to which nipple on that BCS? I tried sticking them on that plug in my palm, that didn't work very well.

 

[RedTurboEclipse]

Or you can get an MBC, EBC and not worry where the lines go.

I already have an mbc. It's disco'd right now as I'm running off my 17 psi actuator until I install my 650s. So the BCS was disco'd for a reason...I thought everyone was saying this was a bad thing. Thanks for clearing that up.

But I still have that mystery plug in that pic in my palm and nobody has any idea what it is. I've been all over that area of my car and there is nothing I can see for it to connect to. AND to make things worse, I found another plug on the driver's side that isn't connected either! WTF

 

[1bad92awd]

Then dont disconnect anything and you wont have these problems just kidding...

 

[5150DSM]

If I had to guess, I would say that's the plug for your foglights.
Aloha

No, it's not the fog plug, those are ziptied already. Whatever it is, it's not causing me any problems so I guess I'll ignore it.
