Hi,
Does anyone know where the oem boost gauge connected to? I heard the line went through the passenger side firewall but i do not see a single line that does so. Bonus points if anyone know the size of the oem gauges haha

 

Back when I bought my 2003 the gauge package was a dealer option. Dealer options were sometimes installed by the sales department. So, picture a car salesman installing your gauges. The line could be anywhere but I'd guess in the grommet behind the glove box.

 

Oh i thought SE's and MR's included gauges, so i was thinking the placement of that gauge line was universal. I have a MR but the original owner didnt include/have the boost gauge

 

In 2003 there was only the GSR.

 

I have an MR 2006 , the boost like ran from the fuel pressure solenoid alone the hard lines towards the passenger side into the fender and through the grommet into the cabin passenger side.

 

I have a factory set of MR gauges if you are interested. Also my line ran in a grommet in the passenger footwell.

 

I think both above posters are talking about the grommet behind the glove box. Under hood it is way to the right, low and almost impossible to see.

 

Look for a vacuum tubing behind the motor, passenger side, right above the alternator, and right below the middle of the strut bar.

 

Pull the glove box if you want to see.

 

Hey thanks the for replies! I think the original owner must have pulled it or something but the grommet didnt have a vacuum line at all. Ive taken a couple pics of the grommet i was looking at and it was just a bunch of electrical wires. I have yet to look at the fpr to find a vacuum line that leads towards the passenger side but ive taken a pic of where i am looking.

 

Hey thanks man. I ended up finding the location of where that vacuum line plugs in thanks to your directions

 

Hey man glad you found it , any other questions feel free to ask.

 

 

tbh, i honestly didnt. i found a spot where the original owner went through which was through the a pillar
