BD cool down timer--hook up on 2005

[Rocky in KC]

Just got the BD cool down timer for my 2005 Dodge----I do not understand what the Purple wire (wastgate Diode) tap goes to??? I see in the print that it ties in with the TAN wire--under the (keep alive) terminal---does the TAN wire and it's tap stay the same????--and what does tap on the purple wire go to--it says ECM power. That is what the tan wire is tapped to???

Do I just hit the Tan wire again with the puple tap???

Sorry for such a newbi question--and thanks for any help--Rocky

really embarrest with all the newbi stuff--but the gauges are working--thanks to all that help--Rocky
