It's
's DD. Also, I had a friend tell me a story about how a person got injured working on a rig that had the start override unhooked.

The Guts
This weekend was the end of all fears. When doing a swap of this type, putting the drive line in easy part. Wiring, until now, was the hard part because I have not been there and done that. But I can say, if I did not know how to read schematics or even have them, this would not be possible. I thought the wiring harness would be tough, but it was not. IMHO, the key to not loosing your mind is to solve one thing at a time. I can truly see the end and it is a nice place to be.
Here is what I got done:
TCC (torque converter control) - The TCC (in the ECM) needs to see 12v when the brakes is NOT applied and 0v when they are. This will tell the ECM when to lock/unlock the torque converter. Therefore when the brakes are applied, the signal goes to 0v and then TCC unlock the torque converter. The brake switch is not wired to do this. So I used a relay to solve this problem. Relay schematics are easy to read but a lot of testing took place.
Electric Fan - I have a Ford Mark VIII fan (same as the Taurus). It is a 2 speed fan. So I ordered a relay kit (see post #1) that not only controlled the 2 speeds, it has a connection for when the AC came on. Total there are 4 relays. The instructions are that came with the kit were straight forward. Here is how it works. The ECM has programing for 2 coolant temperature levels and therefore 2 wires to send signals. When I had the ECM programmed, I had signal 1 set to 165 and signal 2 to 195. For my application, signal 1 will run the low speed and signal 2 will run the fan at high speed.

what you and Mark were there
... no pics no big deal but when I first got it I reached in a started it ... as I stood in the door ... and it almost drove over Mark
woohooo! HOMESTRETCH!!!
Nice build. Are you going to change the dash shift indicator to match the new shifter?

Eventually yes. It's not a real priority now.

Shout out to John @ PSI for walking me through some corrections I needed to make in the harness hookups!
I plugged in the Ultra-Gauge II and pulled 4 codes. P0120, P0220, P1516, & P2135. After JFGI (Just Freaking Googling It) the first 3 seem go relate to each other but when also the last one is added to the mix, it points to a low voltage condition when starting. Since I put a new red top in it, I put on the charger tonight, set it to trickle, and I'll check it tomorrow.
