Ok as I sit here and eat old left over Mexican I thought I would try this and see if it would work. I Got a Juice and Attitude off of a 02 Cummins and I want to put it on a 99 but as it is now I talked to a Edge Dealer today and he said the made no adapters for the 99 Map sensonr plug so I just got an IDEA!! If I knew what wires I had to splice into the original map wires on the 99 I would do it!! The wires on the Juice are as follows. . The female end of the 02 juice wiring has 3 wires and the colors are Brown,Black,Black. . The other plug has wires that are Black,Green,Black. . I have no idea what is on the truck it is dark outside and flashlight batteries are dead. . Then all I have to do is select the 99 in the options list of the Juice for the right Ohm settings YEE HAA. . Will it work or not?? So if anyone knows what wires go where that would be worth a nice COLD BEER or COLA on me of course. . Thanks For the Help. . 573 202 9999
