(yes i did search for like 20 minutes to try and find something but the firewall is a frequent topic that is mostly solved by the hole for the tranny...theres my problem)will what needs to fit through, fit through if i can find it?with correct instructions...is it possible to do in 2 hours...give or take a littleim not an idiot but im no pro (as you can see by my post)thanks for all of the help guys Link to comment Share on other sites More sharing options...

USMC850T Posted March 12, 2006 Report Share Posted March 12, 2006 You can T the boost gauge into the stock line. That's how mine is setup. Link to comment Share on other sites More sharing options...
JHEIII874T5M Posted March 12, 2006 Report Share Posted March 12, 2006 Do not splice into the stock o2 sensor, please, don't do it.If you are going to use that useless narrowband a/f gauge, commonly referred to as a light show, at least pick up a single wire o2 sensor. http://www.atpturbo.com/Merchant2/merchant...tegory_Code=SNS It makes install of an A/F gauge much easier, just ground, power, and tap the single wire off the o2 gauge. on my s70 t5m the firewall passthrough was pretty much in the same spot. , down there underneath the fuse box, just feel around for that big rubber piece with all the nipples on it.

Now take the rubber boot off, then go into the cabin of the car on the driverside, remove the upper kick panel under the dash the pass through comes in just behind the relay panel in the upper left hand corner.

JHEIII874T5M Posted March 12, 2006 Report Share Posted March 12, 2006 Just cut the rubber vacuum hose in half and put it inside the cut, then run the left over part of the T to your boost gauge. Link to comment Share on other sites More sharing options...
