not when boot it surely?

Its a vacuum that reads minus i think, but once you come on boost it will read 7psi roughly if standard...

Should read ZERO when the engine is NOT running, and should read negative when it is idling.

My Blitz controller shows -20 when idling, is normal mate if you've plumbed it in somewhere that reads boost and vacuum.

1 more thing for anyone that might know


got the red wire plugged into to ignition live and the black wire plugged into the black wire on the back of the stereo and got power BUT the light is staying on continuous,surely it should only come on when ive wired it up to the orange wire which it says wire up to the lighting,so when i put the lights on it goes brighter or does it stay bright all the time cos as the moment its on regardless of whether the lights r on or not,plus where is the best place to wire up the ORANGE wire for lights and wot colour would the wires be


thanksagain rick
