18 Pin Secondary Wire Harness (cont’d)
RED/WHITE WIRE - TRUNK RELEASE / 2ND CHANNEL (-) OUTPUT
  This output provides a 250mA negative output when the trunk release/CH2 function is activated 
by the controller� The output will remain as long as the controller button(s) is held�
CONNECTION: Connect this wire to the vehicle’s existing trunk release switch if it is a low current 
negative circuit� If the circuit is a high current ground or a positive circuit, the use of a relay is re-
quired
� NOTE: The built-in horn relay circuit can be programmed & utilized for trunk release 
if not being used otherwise�
