get a five gal propane bottle and a propane regulator and a murphy switch and a hose ran to the intake the murphy switch is controlled by a tago switch or a button style switch mounted under the throtle pedle so when you push the throtle all the way down it pushes the button electricaly opening the murphy switch letting propane into the intake of your diesel me personaly i wouldnt use the tago because you have to remember to shut it off if your not running down the highway

 

TAGO switch = Toggle switch ...... Correct?
