2001 Tahoe, Viper 971XV, DEI 457G

Hi,    I dont know how to install my DEI 457G. My 2001 Tahoe has a passlock with an orange tubing with 2 white wires and I dont know how wire them to the 457G module. MAIN HARNESS Black      to GRound Red        to 12V constant Violet     to Violet of diagnostic plug Blue white to Blue White (status output) IGNITION HARNESS White yellow   - Not used Pinsk/Black    - I dont know where to conect it. Pink           - I dont know where to conect it. I appreciate your help. Thanks so much. Jorge j.f.l.l.

All you use are the 4 wires on the main harness, don't use the 3 wire harness at all on a Tahoe. Mike M2

plus the orange tubing is not your passlock wires and you dont need to worry about where they are....   the 457G will shut off the passlock via data without needing to go to the actual passlock wires.....Kevin Gerry

Thanks a lot Mike M2 and Kgerry. I have another question... Do I need to Program the 457G anyway? Thanks.j.f.l.l.

yes... it still has to learn the R code.... but programming is easier than with the 1700 because you dont need to select a specific platform... it works with all platforms....Kevin Gerry
