Anyone using Add-A-Circuit for power?

As I start to add parts to the car, I now have the JB4, FSB, and Flex Fuel Kit to power. Has anyone used an Add-a-Circuit to power the JB4 and aux devices? I'd rather this than to keep tapping the cables in the DME box.

Thanks in advance!

I have used Add-a-Circuit for my hardwired radar detector.

I have one to power a transmission cooler fan. If you go this route for the JB4 you won't be able to use the steering wheel functions though.

Thanks. I'm going to power it the usual way. But if in the future I do decide to change the setup, I believe I would still retain steering wheel functions. I'm looking at powering the wire that taps the fuse in the ECU box from the fuse panel, not the CANbus. i dont see how moving from a fuse in the DME box to the fuse panel will affect steering wheel controls.

I must have misunderstood you my bad. I had it in my mind that the CANBus wires powered the JB4 and not the third wire that you slip into the 50amp fuse location.

You can also power using the alternate method that BMS provides for cars where the Water Pump stays on and drains the battery. That's tapping into the boost solenoid for power. A google search should find you that fix.
