Message: [QUOTE="co04cobra, post: 1294577, member: 666"] Here's that info copied from that previous link on the cruise wiring. I've used a good bit of this guys info on the 02 stuff and it seems to make most of it work. That post is just on the cruise but he had more info on the TFT tying into the other ECT wire. I knew the factory manual trans trucks had 2 ECTs and the additional one went into the front cover. He put a another sensor close to the water neck, but other then that, I don't recall having to change much from what he had found. Now on to making the Clutch Pedal Position Sensor (CPPS) and the Cruise Control work. Even with the Manual Tranny PCM, the PCM still looks for the Range Sensor on the Auto Transmission to tell it what gear it is in. It uses this information for several different tasks, including starting and Cruise. You have to make the computer think its seeing the Range Sensor when its actually seeing the CPPS. Under the dash tucked up past the Clutch pedal, (its easier to find before you install the pedal), is the wiring harness for the CPPS. It has a plug in it that is called the "Triple Function Switch Jumper". It lets the harness exist, but not do anything because its not needed with the automatic. As far as I could tell, it doesn't do crap anyway. In Order for the CPPS to operate Correctly you will need to run some wires. There should be 6 wires that come into the connector. Personally I reached up in there and cut the harness about 3 inches back from the plug. This was so I could get it out from under the dash to work on it. There is only one wire that stays connected to the harness, and its much easier to add on to it than to work under the dash. Here's what to do with the wires: Red / Light Green - This wire will stay connected to the harness as it was from Ford. You need to make sure it has 12 volts on it in the run and crank position. (2) Blue / Yellow - There are (2) of these on the switch. Connect them together and run them through the firewall to the Gray connector mentioned earlier for the water temp sensor. Tan / Red - Run through the firewall to the Gray connector. White / Pink - Run through the firewall to the Gray connector. Those (3) Wires have corresponding wires on the wheel well at the gray connector. Cut those wires and attach the new wires from the CPPS the same way you did the Water Temp Sensor. Personally I used a short piece of trailer wire so the wires would stay together and have different colors. Tan / Light Blue - This wire is the Speed Control wire (cruise). It cancels the cruise if you push the clutch in. In the automatic, however,this wire cancels the cruise if you push the overdrive off switch. So you need to connect the TN/LB to the overdrive switch. To do this you will need to remove the plastic cover, top and bottom, on the steering column. under there you will find a set of very small wires that connect to a harness and go up to the overdrive off switch. On the harness that the small wires are connected to you need the Tan / White wire. It helps to remove the dash cover to get access to the wire. Cut the Tan / White wire at the harness and connect it to the TN/LB wire on the CPPS. This is also a good time to remove the Auto's Shifter unless you desire to have two! Personally at this point I tried it. Try to crank the truck with the CPPS off of the clutch. It should not crank. You can slide the CPPS back to simulate pushing the clutch in to see if your work has paid off. The truck should crank when you push the slide back. MAKE DAMN SURE YOU HAVE THE TRUCK IN NEUTRAL! At this point my truck did as I was hoping and I breathed a sigh of relief. Now you can put the CPPS on the Clutch Pedal Rod and check your work one last time. Take it for a drive and get above 40 or so mph and try the cruise. Mine worked, and at this point I let out a nice little rebel yell! [/QUOTE]
