Welcome, I'm Chris (aka Moose) I prefer to work when others don't, I am here around lunch and after dinner till after midnight.

Can you go into better detail on how I can help you?

Customer: replied 1 year ago.
I have wiring diagrams but they are not continuous and a little difficult to read. I will look at what I have after work and give you a detailed response. In summary for now, it's difficult to see where power is sent from on the 4 different outputs from c305.

Battery power

Sorry your post was accidentally moved to the wrong category and I could not respond. Here is a connector diagram. Which wires are you asking about?

Hi Moose,
I actually had that diagram and found it useful. Thanks for that.
Now.. I have the Orange wire with Battery voltage on the input side of C305. (I'm getting 12V); The output side is the question. Where and how does the orange wire provide power on the output side? There's literally nothing on the other side (under the car) to provide a clue. Orange wire stops at the input on C305. Where does the orange wire split out to?
Expert:  Chris (aka- Moose) replied 1 year ago.

If you have power in on the orange wire from fuse 24, you should also have an orange wire out on the other side of the connector going to the EVAP canister vent solenoid.

Do you still need help on this concern?

Customer: replied 1 year ago.
Hi Chris,
Thanks for the help so far. I'd like to keep this item open until for the time being if you don't mind. I have some more soldering to do and I just want to be sure I nail it the first time. Unfortunately I'm a (married) driveway mechanic and I may not be able to finish up until the weekend.
Bear with me...
