New Radio won't work after ECU got replaced.

wow. there is no reason you should measure 9.7VDC on that wire (with the plug disconnected) unless there is a problem up-stream. like a bad connection at the fuse box.
bypass that wire - assume it is bad. pull that fuse. run a new wire from the battery to your HU, with an inline fuse at the battery. 12AWG wire with a 20A fuse is sufficient.

Thanks for the help!

Or as an alternative to running a new wire directly from the battery, you can use an "Add-a-circuit" to plug into an unused slot in the driver's side fuse box to power the radio.

I wish I had seen this before I ran the wire from the battery, it looks easier and would have been a little neater then what I ended up with! lol
I'm going to keep trying to find the original problem, if I don't locate it, I may go to this solution just to make things easier.

i wanted you to bypass the fuse box completely with this wire. the fuse box is the suspected problem.
add-a-circuit can be used if you are VERY careful what circuit you choose. choose the wrong one and you can overload that part of the bus and then you have to replace the entire fuse box.
i only use add-a-fuse for devices that draw 1-3A. otherwise i use a spare fuse location or study the schematic for the vehicle to ensure i add it to a fuse that will not be a coincident load (tough to do with a radio).

If the fuse box is the problem, wouldn't I be having other problems?
