This add-on harness can add dual functionality to several Baja Designs harnesses, or simply avoid having to wire through the firewall and mount a switch to the dash. Using a three-position switch (On-Off-Triggered ON), this will allow you to turn the lights on, off, or on when the trigger wire has voltage. To use the trigger wire only, there is a “jumper connector” included that will replace the switch lead portion of the harness and eliminate the need to wire the switch into the cab. The trigger wire is long enough to reach a taillight reverse wire, but also has an intermediate bullet connector that can be used to shorten the trigger wire to reach a headlight high beam wire. The harnesses that this switch lead is compatible with are: 64-0117, 64-0121, 64-0175, 64-0115, 64-0139, 64-0163 Attributes: Brand Name: Baja Designs GTIN: 00810031746088 Application: 4-0117, 64-0121, 64-0175, 64-0115, 64-0139, 64-0163 DES: Trigger Switch Harness Lead Description: Add-on Dual Function Harness EXT: Trigger Switch Harness Lead Mounting Hardware Included: No Product Type: Trigger Switch Harness Lead Switch Included: Yes Switch Type: On/Off/Triggered On TLE: Trigger Switch Harness Lead Universal or Specific: Universal Wiring Harness Description: Trigger Swtich Wiring Harness Included: Yes Extended Information: Country of Origin: US Emissions : 4 Life Cycle Status: Available To Order Packing Information: Quantity of Each: 1 Package UOM: EA Dimension: 8.000 x 8.000 x 8.000 inches Weight: 1.000 POUNDS
