What are these things? Pics included

When I bought the car there has been so many wire cut and just hanging nd i seen these 2 recently nd i wanna know if anyone can help me out my......

Ohh and recently when i try and start my car there are sparks that go off while cranking below the intake manifold kinda where the starter is at...

Then is this supposed to be just hanging like that.....a friend told me that it is bc the guy put the boost guage line directly onto the intake manifold

I can't tell what's in that first picture. Take a higher res and larger picture.

The loose vacuum line in the second picture should be connected to a post-throttle body vacuum port. There is one the driver's corner of the intake manifold body facing somewhat upwards where that line is typically connected. It's the source of air for your fuel pressure solenoid and your fuel pressure regulator and without that your fuel pressure will not rise with boost and you will run lean under boost pressure. Connect it immediately.

From your first pic it appears the bonehead previous owner disconnected this line and connected his boost gauge directly to the manifold like your friend said and left this hanging. Use the T you have there and connect both to that port instead. Yeesh...

I'll try nd up load a better pic on the computer I was on my phone and it didn't let me do in with better resolution

not sure if this is better and when u said second picture in the second paragraph did u mean the second set of pictures?

PIC 5

and is this what you meant by the top corner of the intake manifold body?

I'm stumped on that electrical device. I haven't seen it before. Hopefully someone else will chime in on it.

Regarding the vacuum line in your first picture there in your last post do you see the clear vacuum tubing connecting to the intake manifold? That's the line most likely that was installed for your boost gauge. Disconnect that, connect it to your T, and connect the remaining free port on T to the port formerly used by the clear line.

Can you try and trace the wires off the electrical device and see where they go? It doesn't seem to have any markings on it to use, sadly.

Pic 5 is this.

ok i got the vaccume/boost part that you are trying to explain


but what did u mean by the part about the car running lean if something wasnt connected, not sure if u still see that problem with the somewhat better pics i uploaded

Yes, do this. Remove the line on your T that has a bolt in it, and plug the clear vacuum line into the T and the other remaining line on the T to the nipple you took the clear vac line from.

I have no clue on the first picture.

okay and and doing so will make the car run better or what affect does it have changing it??

or is it to make it look less ghetto??

Pic 5 is this. (My bad. Fixed bad link.)

so i dont have to worry about PIC 5 right? bc i dont have ecmtuning or anything like that

Yes this will make your car run better. With it connected properly, you will get vacuum/boost to your fuel pressure regulator causing your fuel pressure at idle to drop to lean your idle fuel trims up to stoichiometric, and cause your fuel pressure to increase during boost, which is crucial.

Lol um, isn't that the capacitor? It looks like it's been broken at the wire.

I wouldn't worry a whole lot about it, I have been running like that for a while.

ok thanks for the input

First couple go to the A/C compressor; it is the A/C refrigerant temperature switch.

I knew there was a thread running around with it somewhere: http://www.dsmtuners.com/forums/newbie-forum/269945-c-control-unit-ecu-ac-ac-ac-ac-ac-ac-brain-controller-ecu.html#post151894549

Ya, sorry, stupid computer didn't copy/paste properly. Here's the link I meant to paste in there (I'll go back and correct the bad link in a minute).

Ahhh okay I got the A/C connector plugged now


And now I'm going to connect the noise capacitor thingy...

Thanks guys
