Being rained out from working outside on the truck, that gave me some inside time to study the wiring. I have had the 2 books having to do with this particular project open to the PCM 104 pin connector pages and have made a list of wires that will need swapped. There are ~ 30 to swap and in 3 instances, wires to be deleted. That may be enough to turn in to the 4 more coil wires that I will need. I have yet to remove the entire powertrain harness. Also I haven't forgot about the repurposed EGR wire to use for the wide band O2 sensor to use during RT tuning.
The '97 MM 5.0 harness will be used with the '99 crown Vic PCM. I know that there are better PCMs available. This first 5.0 project will be using these parts and the 2003 full size sedan PCM will be saved for the 2nd 5.0 c-n-p project. It's best to have the Ford books to match the exact year and model that you are working on. I felt fortunate to find a 1997 Mercury Mountaineer book.

@ dleach. Correct. Good eye. Fixed like the Mustangs. My '97 Merc Mountaineer (mid year '96) has the detachable oil filler neck. I don't know if I said why that I needed a second driver's side (USA) valve cover. The oil filler neck "hump" is interfering with the coil-near-plug bracket.
Saturday, despite the flood, I went over to work for a short time and prepped and painted the 2nd cover. It's black. Nothing fancy for "Tow Mo".

They also look like the covers on the 94-95 Mustang 5.0 except they are powder coated a silver/argent instead of black.
Iirc, the last time that the 5.0W or the 5.8W was used in a pick-up truck was in 1996.
I've found info that the 5.0 was used up to 2002 in a marine application with even a reverse rotation version produced.
My first thought when I saw these that they were Explorer covers. But I didn't see a Ford Explorer part number.
You can see the 1999 production date on a computer printed production sticker. In one of the pics you can see printed
50SVOA8 The SVO acronym dates back to the Fox body mid '80s. Early use of the SVT name is around 2003?
I saw some "COBRA" embossed 1994-95 valve cover in an internet search.

Current state as of 02-08-24.
Mid-day I was able to remove the console to get to an access cover on top of the transmission hump. 3 out of 4 O2 sensor connectors are right under that cover and 3 of the O2 sensors can be accessed from that direction too. (No pic)
I've been working on the timing chain end of things. It's a good idea on any of the Ford small blocks from 221 to 351W to get out your tap and chase the threads in the block. New double roller timing set in place. Time to put the torque wrench on it. I covered the oil pan opening for overnight. Also I've been keeping it covered when I'm working round it anyway to prevent the oops factor. Timing cover will go on today after the crank seal is installed.
This past Sunday while I was at a swap meat in Nashville, I came across a pair of valve covers off of a 1999 5.0 of some sort. I was needing another left cover to use on the RH side that the oil fill hump was interfering with the coil bracket. After a deep Ebay search, all that I can find in 1999, that uses this very plain stock 5.0 cover is marine 5.0. Wednesday late, I was about to thread on the block adapter from the remote filter kit and it wouldn't go on with the left engine mount installed. Instead of opening anymore cans of worms, I decided to put the stock filter adapter back on. I had previously modified it to fit the FL1A filter.
From the factory it used the metric filter that resembles an FL1A. I purchased a 3/4" doble ended fitting and it fit the adapter allowing me to use an FL1A filter. I will save the remote filter kit for 5.0 #2. The hotrod 5.0.

Great to hear about the performance improvement. Also great to hear about first in your class in your local club and first overall.
I see the Temu link doesn't work because they sold out of the cheap pliers. Mine from Temu look a lot like what you have.

ADDEDAfter looking at your pictures, I hope my cheap pliers have the correct jaw.

This project is creeping but moving forward. I'm half outside with this project so I'm being controlled by the climate.
Before we were all froze in for a week, I picked up a template bracket that was based off of the Riner design. Wednesday I received an email from the fab shop with a pic of the adjusted bracket design for my Mountaineer/Explorer.
One end had to be adjusted because of AC box interference. The bottom was shortened a quarter of an inch from Stephens design and the coils slid up a half of an inch. Also I will be using only 3 holes for the bracket mounting. (Editing comment: In the HTML or whatever language I can't see why it wants to be downloaded as opposed to showing the pic)
I attempted to use a drawing program to make a file to send to send-cut-send but I couldn't ever get the hang of the program. Fortunately there is a really up to date Fab shop 2 miles from me.
Two weeks back when working with the test bracket, I was having a wacky header issue. One "Godzilla" coil blowing right at a header tube. I have found a temporary solution for the RH side but nor the left, until custom log headers can be fabricated. Test bracket is touching the AC box and coil too. Right side manifold to do away with header interference.

OIC. I'm not supposed to go to GitHub to use it, just download it. Thank you for the pointer.

A second question would be, If I'm looking to turn off the rear o2 sensors because the catalytic converters are removed, Is this strictly because I'm trying to prevent the PCM from throwing a code and turning on the check engine light or is it deeper than that? like preventing the PCM from switching to open loop mode which and tell me if I'm wrong, or "limp" mode?
After sleeping on it last night, I wonder if I'm actually putting the bin file in SAD correctly, but it is as simple as not labelling the new file correctly?

2 months ago, I successfully created an _lst file with SAD. Now when I do it, it looks like a bin file name. What am I doing wrong?
Copy this image that I captured and circle the spot where I need to drop and drag the bin file.
Also, when using SAD, should I start with a 256k 0-1-8-9 bin file?

I've spent the last two hours trying to relearn what I learned in early October, running a bin file through SAD. Finally I got it.
I thought I might give it a go trying to find out how to turn of rear o2 sensors. Also, I don't know what I would be looking for as far as the rear o2 sensor/s are concerned. Clearly, I don't know much about what I'm doing. I'm still trying.
Add to your list of quality pass through devices, the Made in Spain Scanmatik 2 Pro device works very well with the PCMFlash software. Is it technically Russian or Kazakhstanian software?
