[QUOTE="IHPowerstroke7.3, post: 1250617, member: 7642"] That is correct, same circuit is used. Looks like pin 37 at PCM, Orange/black. Auto PCM looking at TFT, Manual looking at Coolant Temp. However it looks like the TFT signal is sent to the cluster from the PCM over the SCP network. Also there is a second coolant sensor that is wired direct to the cluster. I would think it would be best to use actual coolant temperature as the input to the manual pcm though as it would have an effect on tuning, but I'm sure you're way ahead of me on that. [/QUOTE]
