SignUp Now!It's not necessarily a sign of any trouble. There is a Hobbs switch mounted on the passenger side fender. Make sure the vacuum line is still hooked up to it and check the connector on it.
I have no idea when the lights are supposed to come on, but mine start to light while I'm still under vacuum. The switch can be adjusted but I'm not sure how.

I believe this is a 2 bar map sensor.....not a hobbs switch. A hobbs switch has only a contact that opens or closes at the "set point" for vacuum or boost. The Map sensor has a variable voltage output that changes with boost. I believe it varies between 0 and 5 v.

The 2 bar map sensor is on the analog dash cars. The digital dash cars have a pressure switch with two contacts. This is a digital dash car.
I stand corrected.... I had my head up my @ss I guess......
Carry on...... :redface:
