I too would say that the red wire is positive however it is the coil pins that I want to know which is which.With the coil turned up in its mounting position, is the left pin positive or the right pin?

Thanks d. Good pic.

Here is a PDF of the coil connector from the EVTM.

For good measure, here is the wiring page

One more "Godzilla" coil question. What is the pitch of the thread of the M5 bolt? I FINALLY got my c-n-p brackets.

2 weeks ago, I got off to a good start on the wiring harness before the label maker ran out of tape late last weekend. It was several days before I got back to work on it. It took some time to figure out where I was on it. The most logical approach that I came up with was work from the back to the front. I started with the VSS. There will be some kind of difference between my '97 Merc that reads the speed off of the transmission and the "99 Crown Vic reads the speed off of the differential. I would imagine a tuning adjustment will need to happen as it has to do with this.
I'm eliminating the rear O2 sensors. That freed up 4 wires that I used to add 4 more coil driver circuits. I have 95% of the 104 pin connector sorted and rearranged. There were close to 30 wires to move. Only one ground wire had to be lengthened in order to be moved. I'm a bit confused about the transmission wires and I appear to be missing one. I have been through the charts in the books and here is what I have for the 4R70W.
* 97MM pin #1 Shift Solenoid #2 moves to 99CV #11
* 97MM pin #27 Shift Solenoid #1 moves to 99CV #6
* #29 Transmission Control Switch stays the same
* #37 Transmission Fluid Temperature stays the same
* #54 Torque Converter Solenoid stays the same
* #64 Transmission Rage Sensor input stays the same
* #81 Electronic Pressure Control (EPC) the same
Here is a wire that I'm unable to find on the 97MM. The 99CV 104 pin chart has a pin #34 wire num 1144 Y/B wire that is missing on the 97MM chart.
Charts below. After the pictures will be the short list of odd, loose pin wires.
1997 Mercury Mountaineer 5.0 104 pin chart. 1999 Ford Crown Victoria 104 pin chart. The following wires are loose at the 104 pin connector and i'm not sure where they go. The EGR wire will get repurposed for the added wideband sensor? This is kind of a question and I'm not sure how to do this.
* A 97MM wire #30 solid green Octane adjust shortening bar adjust. Not seeing a spot for it on the 99CV PCM.
* A 97MM #63 O/Y EGR/EVP I'm not finding a spot for it.
I'm about bug eyed and need to take a break for a bit. I'm going to go clip the park/neutral range switch and connector off of the 99CV harness. There is an upgrade to the later style transmission wiring that has to happen too. I hope this will help me back trace the wire 1144 Y/B wire issue.
Any extra eyeballs would be appreciated.

This afternoon after clipping the 12 pin newer style DTRS transmission connector off of the end of a 1999 CV harness, I see the YE/BK wire #1144 and I see that a wire will need to be added or repurposed. I'm set up with a list of all of the transmission related wires as well as the 12 pin connector. In the morning on a fresh coffee head, I will visually check each wire at the transmission and at the PCM end of the harness. It shouldn't be difficult to deal with because at least 5 are in their original spots on the 104. C-111 I think it is called will need some changes too.

* A 97MM wire #30 solid green Octane adjust shortening bar adjust. Not seeing a spot for it on the 99CV PCM.

This will not be present on the CV harness/pcm, They do not have an octane adjust input.

* A 97MM #63 O/Y EGR/EVP I'm not finding a spot for it

This one is for the egr vacuum solenoid on the MM, should be pin 47 BN/PK ckt 360 at the CV PCM to run egr Vac solenoid. But if you are deleting EGR you will not need that one either.

I had finally decided if the '99 CV didn't have the spout, it was ok to delete it.
I am deleting the EGR and I've read something somewhere about using this wire with a wideband sensor with the QH in a real time tuning situation. I will go back and read Michael's info when I'm near finished with the harness.
I have determined that I have to add 3 DTRS wires that my 97 MM harness doesn't have.
As simple as it would seem to be, I have a 97 MM ECT wire to find a home for in the 99 CV pcm.
Today, I trial fitted the rh coil bracket to be able to pick a spot for the 1/2" pipe thread oil fill bung. I sourced some aluminum tubing to make bracket spacers. A 1/4" bolt fits through it well.

The 99cv used a cht sensor and did not have an ect sensor. Not sure if you can change the code or something in the tune to compensate for coolant temp instead of metal temp. But the ect wire may just be hooked to the cht pin. But you should verify that with someone who has done the swap already.
