Here is a few pics of the location. It's a PITA to get at.

Those wires go to a sensor of some kind. Or so it looks on my car. Not sure if they are knock related since it's on a fuel rail or something.

Then again i don't have the diagrams to confirm.

Ask and you shall recieve.

I just wanted to add, at the track last night most of the runs were 0KR with a max of 1.5 on a few long stages. I did in the past have a few freak 3.5 KR before. The hour trip up and back I saw a max of 1KR and that was probably due to being stuck in traffic on the way back due to road construction. It looks like the wire was the fix!

Finally did this today.  Had some blue wire loom so I used it.  Cut about 6 inches and slid it over both wires.  Put a little tape at the top to hold it together.  Not in the photos.   They did change how the wires run it seems compared to the photos on the first page. Possibly longer wires even.

Quality job!

I also put a wire loom over it a while ago,and also found a 1/4 breather hose sitting on top of the TSTAT HOUSING which was partially melted and changed the 1/4 hose and put a 3/4 wire loom over it,hope this helps someone.

Nice pics!  What lighting do you use?

That's not good, glad you caught it!

Combo of a nice twin bulb matco work light and phones flash. LG G2

I've been seeing KR in pulls when it really shouldnt be there, especially now with E85 and 93 Shell V-power mixed. Did this on the driver side, and a KAM reset, hoping once the car fully relearns everything that I'll see 0 KR, as I saw a bit of KR during a WOT pull after doing this. However, I am also seeing negative KR a lot more than previously, which seems promising.

Does anyone have more pictures/recommendations on how to get to the wiring on the passenger side?

Ford the drivers side, I just put 3/8 inch loom over the lower section, and over some of the OEM covering below as well. And taped the exposed part on the top part of the connector. I also unplugged, and re-plugged it on top of the boost/vac reference line (one ZSHO mentioned had melted) to move it away from the block. I also wire loomed that boost/vac line, to prevent it from melting.

Here is great thread posted by Shoboat a while back and glad to see my post above helped out a bit.  Z  http://www.ecoboostperformanceforum.com/index.php/topic,4833.0.html

Thanks Z. That's the one I got already though. I believe there is a second one near the throttle body, that I am unsure how to get to.

If your knock sensor wires check out and the knock is fairly "new" I'm guessing you may be running in to winter gas blends.  I mix E85 and BP 93 premium and in the summer easily see 4 degrees of advance (limited by the tune) on the knock gauge.  Now with winter gas (even with mixing) it barely budges above 0 and I see spark retard in the 0-4 (with an occasional spike to 6) range.  It happens to me every winter...I will probably switch over the 91 octane tune and just run 93 in it for the winter as I hate mixing when it's super cold.

The KR seems to have been there since I started tuning. I ran 87 for a while on the stock tune, then 93 for a bit, then tuned it. OAR was -.96 for what seems like an eternity. I started blending, 3 gallons of E-85 and the rest 93 Shell V-Power and OAR stayed consistent. However, currently OAR is going down, and is at -.81. I am thinking there may some winter blend at play as of now, due to the OAR going down, or I got a bad batch of E or the V-power. Not super sure, but will probably return to Sams Club 93 once this tank is empty, as that was always a consistent -.96 OAR.

Welcome back stranger!!...sure miss your posts.  Z 

Thanks Z! I've been lurking on and off. Ended up buying a 2017 Victory Octane (motorcycle) and have been working on making that faster. Barely drove the SHO this summer...missed it though.
