I couldn't find a thread with this information, and a buddy of mine was dealing with a situation in regards to this today.
2005 Dodge Diesel, engine light came on. Active code for Wastegate actuator circuit. He found a resistor, but it was so badly burnt up he couldn't see and marking on it to determine the resistance. After some searching online, I found two values. One thread that said a 100 ohm does the trick, and another that said 140-150 works. Both claimed they should be 1.5 Watt resistors. The latter thread also had a measured resistance of 147.6 ohm on a brand name fooler.
The reason for the resistor is to keep the computer happy (fooled), when a different turbo is installed that does not have a wastegate actuator. Another option, if you are keeping the factory turbo, is to keep the actuator plugged into the harness, free from the stock turbo.
My buddy installed a 100 ohm resistor, and the code went away and truck drove normally.
Hope this information can be of use to someone, and is easy to find in the future.

Wastegate actuator fooler.
