Im installing my aem wideband,my question is,how do i get the big piece,that connects to the sensor through the firewall,i see the gromet,on the driver side,but was curious on,if there was a bigger opening,to put it through,or do i just push it through the gromet on the drivers side,

 

i ran everything behind my glove box and ecu there is a big grommet there...just unplung the the wiring from the back of the gauge and run the wire from the outside into the car

 

so there is a grommet behind the glove box,cause i ran my boost line and aem line,through the drivers side grommet,but was curious about the harness,trying to figure out,how i would run it from outside to in,or vise versa....

 

Wow so bigger hole by the glovebox? Thanks for the note!

 

I ran from the outside in so I didnt have to run any sensors through the firewall just the wires

 

so where exactly is this grommet,i know i have to take out the glovebox,is it some where that cant been seen unless you move some more stuff,

 

Yea you have to pull the ecu out it right behind it

 

thanks man,that was alot easier,

 

no problem....happy to help out
