Auto to Manual Swap 2002 F350 NIGHTMARE, please help
I have read several write-ups on Auto to Manual Conversions. I went ahead and did the swap. One thing I did NOT know was that 2002 was the year for did a wiring overhaul. I also didn;t notice that all the other trucks were 1999-2001.
I have an Check Engine Light On. the cheaper Actron scanner says "no codes" but the SnapOn says other wise. I had the Computer reburned for a Manual Transmisson too. There were supposed to be 2 pairs of wires on the Automatic's gear selector switch(DTR Digital transmission Range Sensor) plug that I was supposed to be able to tie together... only two of the wires match the other guys writeups, I don;t have the other colored wires. SO to get the engine to start, I took the gear selector switch off the Auto Transmission and just put it in park and ziptied it to the frame.
The truck is getting about 8 MPG.....
It started snowing today out here and so I noticed that the 4x4 does not work either (I kept the electronic shift T-Case and just swapped out the input shaft to fit the Manual.)
One thing I notice, is on The last two pages it shows PIN 37 on the auto being the TFT Transmission Fluid Temp but it shows the Manual as using that pin for the EOT Engine Oil Temperature. Pin 38 is also used for the EOT on BOTH the Manual and the AUTO. The sensors, according to the dealership, for the EOT and ECT sensors are the same for both auto and manual.
Page 124 and 126 confirms this. But I don't understand where/which wire on the trans connector plug is for the trans temp, and where should is be spliced into the EOT sending wire. It's LIKE on the Auto it comes out of the PCM and goes straight to the trans TFT sensor, BUT on the MANUAL, it comes out of the PCM, goes to the ECT, goes out of the ECT, goes to the EOT/EBP/ACT/& Injection pressure sensor. The CODE that the Snapon brings up is "P0118 Circuit High Input)..... If you know what is going on here, please spell it out to me, I'm dumbfounded... it's like I found the problem and don't know how to physically fix it.
Page 88 shows something else I don't understand. The Manual has an "Auxiliary Powertrain Control Module" (APCM)... What is that? does my auto truck have it? do I need to buy it and wire it in? if so, where?
Page 140 shows some 4x4 stuff that I don't know what to do with.
Page 221 shows me the black/pink wire that goes to the plug on the manual trans so the reverse lights work.... not a real big help.
Although I'm not concerned about the reverse lights and cruise control, the cruise control needs to get tweeked too. I read this "There is a communication line between the pcm and clutch position switch which even if hooked up goes to a different pin on the manual pcm. Pin 29 for the auto harness has a tan and white wire which hooks to the OD cancel switch. On the manual pcm, that same wire is for the clutch position switch. If you take the Tan/WH wire from the cancel switch and connect it to the tan/LB wire from the clutch position switch, effeectively you give the pcm back the signal to cancel/engage the speed control." I don't know what or where the cancel switch is, but I hope this fixes the cruise when I get to it.
Please help me fix my mess. It doesn't look like there is THAT big of a difference between the MANUAL & AUTO but there must be more that there is on the 1999-2001's
Heres another link to the wiring PDF incase the one above doesn't work.
Here is the list of codes I am getting from the SNAPON after it runs its tests:
PCM MEMORY CODES
-P0118 ECT Circuit High Input
Cluster Memory Codes
-B1318 Low Battery Voltage at Module
-U1027 SCP DATA Fault for Engine RPM
-B1352 Ignition Key-In Circuit Fault
-U1262 SCP DATA Fault for J1850 BUS
ABS Memory Codes
-C1230 Rear Speed Sensor Circuit Fault (This one actually is right, I think the sensor went bad, speedo still works though)
GEM/SJB Memory Codes
-B1359 Ignition run/ACCY circuit Fault
-P1865 T-Case Contact PLT Power Short Ground
-B1483 Brake Pedal Input Circuit Fault
-P1876 T-Case 2wd Solenoid Circuit Fault
