30-5132 trouble sensor


I install on my Supra a analog boost gauge 30-5132 BRAND NEW, and the left light flash and no autozero, the needle is positioned at 6 o clock...

After pass a lot of times to check wiring, i dont find a problem...

2 RED on 12Vpower

2 black on ground

Pink on ignition 12v power source

Grey on instrument light

no connect brown and white on my ems V2

I checked the continuity of wiring between gauge an sensor, RED/Black/Green its OK

I measure 1.57V between green/black sensor and 5.00V between red/black when i switch ignition. Sensor seems OK!?

I dont know what to do, can you help me?


Many thanks
