Let me starte off with im new to the FD world.
Not looking for special treatment, just pitching that out there.

We have owned this FD for a short time now and are just trying to get it reliable for a DD for my little brother.
Car is Twin turbo so we istalled a Prosport Boost guage i had laying around.
I tapped into the "exhaust over heat" indicatore next to the security indicatore. seems that the guages LED is lighting up when the car is on, but when you start the car is flickers and the LED doesnt light up anymore.

Any other ideas on were to tap in for a safe power draw? I could go mess around and do what i want but i just wanted some insight since its not really my car its my little brothers and i dont want to short out fuses or links.
I was looking at the cigaret lighter but seems hard to get to.
We also have a AEM wide band guage to install, Prosport oil pressure and water temp. (also may use the DEFI WATER>OIL>BOOST guages insted of the prosports idk if i want to give them to him yet )

Also friday we are installing his new Tein Flex ED coilovers, Tanable sway bars, GFgoodrich Gforce KDW, and cusco strut bars.
