You have to take out the instrument cluster. You will only have a few inches to get your hand back ther and turn the clip out. It is a pain in the ass to get it back in. the line will just barely reach so if you have some one to push on the line from the fire wall it will give u more slack.
it was easy i did it myself no help i just put it through the fire wall it went into plase and i pulld the line and it snaped into place
