Constant 5v Source Anywhere?

[94GrandPrixSE]

I Need a regulated 5v source for my Aeroforce air temperature sensor kit, any suggestions? other than buying a 12v to 5v DC regulator?

Add a circut dealio to a fuse in the glove box.

I pick the IGN fuse or the radio, both get power when the car is on.

I thought that was a 12v source no?

 

[Fivefingerdeathpunch]

Hmm, I guess you're right.

Then I'm not sure were you will get just 5v unless you tapped into a sensor that only is supplied up to 5v.

The EGR is a 5V circuit right? if so is it a steady 5V? or 1-5V?

It's 0-5v

There are regulated 5+'s off the pcm. You'd need to find the thread with the pcm pinouts and find the right circuit

I thought there might be a 5V source on the obd2 plug, but I'm not sure. do you guys know?
