I would suggest that you evaluate focusing on the C115 connector. Outside the engine/transmission harness that is the gateway to the rest of the vehicle. Other than the high current alternator/starter circuits everything in the engine/transmission harness goes through C115. I started with a '00 302 with the original transmission, harness and PCM. The pin out of that connector and various electrical schematics can be found here:

The engine management electrical schematics are there also. I have the Ford schematic book and can get you anything that you think you need that is not found at that link. I can't help on the vehicle side of the wiring.
Chapter 12 of the Volvo/Ford swap manual (
http://forums.turbobricks.com/showthread.php?t=250746) describes all the connections necessary at C115 in about a dozen pages of posts but can be summarized to these 19:
C115M pin out – short version
1.) Pin 1 (red/light green) (circuit 16, page 13-16) Ignition coils power
2.) Pin 2 (tan/yellow) (circuit 11, page 62-2) Tachometer
3.) Pin 3 (pink/light blue) (circuit 915, page 25-6) Data port
4.) Pin 4 (red/light green) (circuit 810, pages 30-2, 59-6) Brake torque converter unlock
5.) Pin 5 (dark green/yellow) (circuit 238, page 25-1) Fuel pump on signal
6.) Pin 6 (pink/light green) (circuit 658, page 23-2) Dash MIL/CEL
7.) Pin 8 (yellow) (circuit 37, page 25-1) PCM permanent B+
8.) Pin 9 (red) (circuit 361, page 25-2) Fuel injector/IAC/MASF B+
9.) Pin 11 (tan/orange) (circuit 914, page 25-6) Data Port
10.) Pin 12 (tan/white) (circuit 234, page 30-2) Transmission Control Switch (OD Lock out)
11.) Pin 15 (light blue/orange) (circuit 926, page 25-1) Fuel pump relay
12.) Pin 16 (red/white) (circuit 39, page 62-2) Coolant Temperature Sensor
13.) Pin 22 (violet) (circuit 107, page 14-1, 25-6) PCM reprogramming power from Data Port
14.) Pin 26 (dark green/white) (circuit 253, page 62-2) engine oil sensor
15.) Pin 34 (black/white) (circuit 570, page 10-2) Ground
16.) Pin 36 (light blue/orange) (circuit 34, page 13-5, 25-6) O2 sensor/transmission power
17.) Pin 40 (white/light green) (circuit 911, page 62-6) 'OD OFF' indicator light
18.) Pin 41 (light green/red) (circuit 904, page 12-1) ALT light
19.) Pin 42 (yellow/white) (circuit 36 page 12-1) Alternator power
These circuits were all that were necessary for my swap. Your mileage may vary.
The two versions of the Cam Position Sensor both provide a signal on a shielded wire to the same C202 PCM lead. Since the early PCM can be reflashed to use the the later software that suggests that it is not the sensor output to the PCM but the manner in which it is generated. What ever your engine has should work. The only issue would be if you have the early sensor and the late harness as there would not be B+ power in the harness.
No mention of CKP problems have come up to my knowledge.
Let me know how I can help.
