i recently purchased an a/f gaugeto fill a blank in my pod until i get an intake gauge. a wiring diagrm for an 02 wrx refered me to this diagram which i rewrote into here.

my battery is disconnected and the harness disconected... id really like to get this gauge in tonight so i dont have to do this all over another day and still have a blank spot on the gauge...

any help would be appreciated...

Front oxygen (A/F) sensor

Sensor (–) D29 B 2.4 — 2.7 2.4 — 2.7 Positive voltage to sensor's (–) terminal
