Does the evo one need the passlock bypass hard wired? Or does the flash link 4 bypass the passlock with data? The diagrams for the evo one in a 03 Silverado 2500 doesn't show wiring for the passlock bypasss. Does the evo one need to learn key data first in vehicle then hook up flash link 4 or will you flash evo one first?

Immo bypass is done through the OBD-II connection. 

Be sure to use firmware 70.18 as stated on page 1 of the guide.
