Howdy Gents! Took the PLX plunge and installed a Wideband Sensor and DM200 today. Everything wired up and....no power to the gauge.

I'm going to tackle this again tomorrow and see if I made a mistake anywhere but where/what did you use as the source for your power for the devices:

Current wiring Scheme:
1) Double checked that AFR SM was jumpered.
2) Checked connection from SM to DM was correct
3) Using a switched power source in the fuse box under driver side.
4) Ground is on the driver side foot well area as well.

Suggestions? Thank you!

Ask goodfellas. He installed mine. Did you look at the PLX thread David Hayes posted btw?

my plx m-300te power is wired to a fuse in the driver side footwell too. pretty sure its the top middle one (sunroof?).

maybe try a different fuse and make sure your ground has a good connection.

Break out with you multimeter and make sure that you have power.


Mine are hooked up to the fuse box

I actually ended up using a spade connector to pull power from the slot that is on the top right, directly above the fuse box. Found out about it in an old thread. Seems to work great. Any reason why I should use the fuse box over this in anyone's opinion?
