There are several dudes over here
Dodge Diesel - Diesel Truck Resource Forums - Powered by vBulletin that have done it and they have write ups on it... I don’t think that I have found the correct resistor and where to install it though... I might have not looked around enough and not done all my home work
But if you are looking for the info these guys will get you almost to the finish line and get you much closer. If you’re interested.
If you find out where/when/who/what to buy/where to stick/to make it work...... will you post your findings, maybe with pictures?????
THANKS !!!!
