Does anyone know of the top of their head how many amps these two would draw? I am thinking of attaching my heated wide band sensor to the O2 heater wire, that way it is only on when the car is started. My instructions say it draws 1.3 amps, do you think I will be safe on that circuit with the 15 amp fuse?

I am just going to add a new fuse for my WB system, if something goes wrong I don't want it to take out my FP

The factory O2 sensor runs on that circuit so the same would be true for it, if it shorts the fuel pump would quit as well.

Yes that is true if you’re replacing it then do it. I’m going to run two, the stock NB and a WB.
I may remove it after she is tuned and use the set up to tune my Turbo Mini

I believe the main FP take about 10A.

I am sure you will be OK to connect the WBO2 on that circuit. That is what many SharkTuner customers use with the harness I provide for the purpose.
