Will the fitments/wiring of different types of boost gauge be the same?

i.e. - if i bought a different make of gauge to replace the one I have, will it be a case of just disconnecting one, then re-connecting another?

Probably not I'd imagine, as nothing is ever simple!!

Cheers

 

i had a cheap crap boost gauge on the cossie when i got it an it read -10 psi on idle and 30psi on boost i replaced it with a ford raceing gauge now i have -19 hg someting on idle and very confused

 

Should just be able to put a new one in if it's mechanical - if it has a sensor, then you'll probably have to change gauge and sensor as the sensor may be calibrated differently.
