where can I get a boost guage with minimal hardware installation, (if electronic boost guage has this, which one). I dont want to run hoses and other cabling into the firewall if there is a boost guage you can simply tap into wires that are there from manufacturer.

maybe a link to where you guys bought an electronic boost guage...

 

Pretty sure you're going to have to tap into a vac line regardless of what guage you get.

 

Defi blue racer.

 

it reads off the ecu, correct?

so that would make it 100% accurate?

 

No.There's a remote sensor in the engine bay,all you have run through the firewall is a small wire from the sending unit,boost is hooked up in the engine bay.Also the Defi doesn't require a seperate controller.

 

What hole in the firewall did you route the the wire from the sending unit? It seems like this wire is too short to put through the passenger side grommet hole near the glove box.

 

There is more than enough room. I went through the grommet in the passenger side and had to zip-tie excess wiring. There is PLENTY of wire to reach

 

Nice looking guage!

 

you're right! i found this out for myself last night too, though it took half an hour to find the grommet after i dropped it in the engine bay

 

The prosport gauges i sell are the exact same way, they have the electrical version which has a sensor installed in the engine bay which you connect to the boost gauge in the cabin...or they have the mechanical version that you run a small vacum line too...both are easy installs...
