Yup.....Dats what it looks like. See my "added info" in my reply. Stopped by Kav's and looked at it. 500w Farad.CAP.?
now how to kill...You have CMC, the noise is on the coax braid.
All I know is fan unplugged and noise down, about 90%over 1000rpm.It is odd that disconnecting the fan removes 90% of the noise. In my experience the engine cooling fan (I assume that is the fan that you are referring to) comes on under just a few conditions-
1. Engine cooling temperature reaching a pre-determined threshold (ex. 190 degrees engine coolant temperature)
2. ECM detects a "Hi Pressure" reading in the A/C line (Signifying that the air conditioner is on and the condenser needs the air flow)
3. Combination of 1 and 2 above putting the engine cooling fan into high speed.
If the fan is not running, such as initial cranking/running of the engine from cold start, I don't understand what could be causing noise/interference when disconnecting the fan motor??
Not trying to be argumentative here or casting doubt on your findings, just trying to understand.

Plugg back in...noise is back.
I think I may have found something out about a "side air bag"sensor after digging around under the dash( had to remove seats)that is now on and off (light on dash).Very odd. Without the fan running, current only travels as far as the cooling fan relay. It is on "standby" until the ECM turns it on. Unplugging the fan motor still leaves current traveling only up to the fan relay.
Brushed or brushless motor issues???? Power wires acting as an antenna and motor as the "noise" transmitter???
I could replace the fan.....But now I have a sensor showing up..... I need to think for a few days and get back to it.Can you replace the fan?
Thinking the noise issue in more in the fan assembly itself - meaning the fan is the noise - no true means to clean that up unless you can replace the fan and examine the harness for damage.
saw that too. I am given it a day to think....I had to remove the seats to get under the seats...I am 6 .3 1/2 260 and a Honda is tight inside...Maybe a small disk capacitor on the fan wires? It will shunt the noise to ground. I read somewhere that someone did that to their fuel pump.
