Im gonna buy the Defi gauge this coming week, the Defi-shop website gave out instrutions in where to "LOCATE & INSTALL" by any chance does anybody have the "OUTLINE PICTURE" for the FC....? the instructions don't look to hard, i did research on the MAZDA REPAIR MANUEL" i checked the glossary to Locate and correspond to "which & where it connects to?... but i can't make anything out....

does anybody have pics/any hints ????

 

Tee it off of a vac source. Easy.

 

erm, the BF is electronic isnt it?

I have the Defi D-Gauge for my boost gauge. The mechanical one.
I tee'd it into the BOV line that comes off of the intake mani, just cut it about halfway and tee'd it and put on a bunch of zipties.
Yours is electronic i think so you just have to run that line to a sensor and that will stay in your engine bay.
I ran my vacuum hose through the firewall in a slit in the ABS boot, which is above and to the left of the turbo, about a 1.5" boot. Then just try to feel it out from underneath the dash, it's there, you dont have to take any dash apart. Then theres a hole behind the stereo that is open from one side to the other.
The rest is up to you big pimpin

I tied into the cigarette lighter light for my driving light power source. Very easy to get too.
Don't crack your stereo surround there are 2 screws behind the vents at the top and 2 behind the ashtray.
I did mine w/o taking the top screws off, just pulled it out a couple inchs. Was a pain in the ***.

 

lemme know if you have any other questions about that

you can use either the BOV line, or the pressure sensor line. either will work.

Be careful not to break any of those lines if theyre original, I replaced all of mine with silicone.

 

You'd still have to tee it into a vac line or at it's only independent vac source.

 

Im also getting the water gauge as well, how do you intall that??? QUOTE=Node]erm, the BF is electronic isnt it?

sorry man, only installed the boost gauge. as for the watergauge i think you just use there sensor in the stock water temp sensor location. not really sure

and yeah i know you still have to tee it. just saying you dont have to run the vacuum line into the cabin, but you have to run the elctrical lines still
