  21. shr-illuminated-push-button-start-ignition-kit-blue-10-12-all

    ** DECISION TIME ** If you want the switch to be illuminated only when the emergency brake is set and the key is in the ignition. follow steps 16-19. Otherwise. skip to step 20.

  22. If car is equipped with a manual transmission, remove shifter knob by rotating counter-clockwise. If equipped with an automatic transmission, using a trim removal tool, gently pry shifter bezel from around automatic shifter and remove.
  23. Open center console cover door, reach under center console cover, and unclip / remove center console top section. Disconnect wiring as needed for traction control, ambient lighting, etc ..
  24. Remove (2) 7 mm bolts at bottom of radio / HVAC controls face.

  26. Continue Disassembly

  27. On passenger side, open glove box, squeeze sides to release stops, and swing glove box down to fully open position
  28. Locate 8mm bolts (2) that hold passenger airbag module in place and remove. Any auxiliary modules in the way need to be removed for access to the airbag bolts. (Fig. 6)
  29. shr-illuminated-push-button-start-ignition-kit-blue-10-12-all

  30. Disconnect passenger airbag connector located behind the passenger airbag. (Fig. 7)

  34. Remove center register from dash, and disconnect aux. power outlet plug wiring connector & safely route / secure. Wiring will not be re-used.
  35. Remove the aux. power cover door from the center air register assembly.
  36. Place center register face down on a towel, and release the clips holding aux. power outlet in place. Remove aux. power outlet - it will not be re-installed. Screwdrivers or needle-nose pliers may help aid in removal.{Fig. 8)
  37. shr-illuminated-push-button-start-ignition-kit-blue-10-12-all

  38. Use a small screwdriver to release the clips holding the "push-hold-push-release" door mechanism in place and remove. This is the little 2-prong retainer that normally keeps the aux. cover door closed. (Fig. 9)

    Wiring and Pre-Assembly:

  40. Route switch wiring through existing power outlet opening in center register. Snap the Tru-Billet switch plate into the existing dash pins that held the original auxiliary power outlet door, and using supplied .050" Allen wrench, tighten set screw to hold Tru-Billet plate in place. Check alignment of plate with face of registers and adjust if needed.
  41. ** DECISION TIME ** Decide how you would like switch to illuminate (if at all) and follow the appropriate wiring instruction (30-32) for the ground wire below:

  42. If you would like the start button to be illuminated when the key is in the ignition & the emergency brake is set. the ground (black) wire must be pulled from the switch harness split loom and safely routed separately with existing vehicle wiring to the emergency brake switch in the center console. Use supplied zipties as needed to safely route the wire and keep from any sharp edges. Wire will be connected to parking brake switch pin 1 (white wire with violet stripe Fig. 10).
  43. shr-illuminated-push-button-start-ignition-kit-blue-10-12-all

  44. If you would like the start button to be illuminated continuously when the key is in the ignition (constant on), the black ground wire will need to be connected to vehicle ground just below instrument cluster near steering column. Keep wire in conduit and only pull it out far enough to reach the distance between the ground point and the steering column ignition switch in upcoming steps. This ground can be shared with any other common ground nearby on the metal portion of the dash.
  45. If you do not want the switch to be illuminated at all (constant off). safely terminate the ground wire inside the conduit, and do not connect it to any vehicle ground.
  46. Continue wiring:

  47. Red and green wire in conduit (and black wire if following step 32) will need to be safely routed from center console to steering column by routing with existing factory wiring.
  48. Once routed, using supplied tap connector, connect Red wire to Pin 5 of ignition switch (Blue wire with grey stripe tracer Fig. 11)
  49. shr-illuminated-push-button-start-ignition-kit-blue-10-12-all

  50. Using supplied tap connector, connect Green wire to pin 7 of ignition switch (Blue wire with white stripe). Important - if you would like car to start ONLY with use of button, cut wire as it exits pin 7, allowing wire as it goes back into the harness to only be connected to green wire. If you would like it to be "dual purpose" and be able to start either with the key (as original) or with the start button (preferred installation method), DO NOT cut blue/white wire, just safely tap into it with supplied tap connector.
  51. Once wiring is connected, reconnect ignition switch connector and safely route wiring away from any moving parts. Zip tie to existing factory wiring with supplied zip ties and trim as needed.
  52. Reinstall center register in original position and install 7mm screws.
  53. Reconnect HVAC control wiring, and re-install center console cover. Re-install (2) 7mm screws at bottom and tighten.
  54. Testing: For the following steps. be sure vehicle is in park if an automatic. neutral if a manual. wheels are safely blocked. and emergency brake is set.

  55. Temporarily reconnect battery negative ground cable.
  56. Sitting in driver's seat, place key in ignition. If illumination ground wire was connected to emergency brake wiring or directly to ground, start button should illuminate. If it is wired to do so and does not, re-check ground connection.
  57. If switch is wired to turn off when emergency brake is released, test for proper operation by doing the following: hold foot firmly on brake pedal and release emergency brake. Illumination should turn off. Set emergency brake and switch should re-illuminate, along with parking brake warning light on instrument cluster.
  58. Turn key to on position, but do not start. With transmission in neutral (manual) or park (automatic) and foot on brake, press start button. Engine should start. If it does not, remove key and re-check connections. If engine does start, turn back off.
  59. If blue-white wire on pin 7 of ignition switch connector was not cut in step 35, check for "normal" operation with ignition key by attempting to start with key only. Engine should start. Turn engine back off after testing.
  60. If above tests are successful, remove key from ignition and disconnect battery ground terminal. Wait 5 minutes before proceeding with re-assembly.
  61. Re-connect traction control/trunk wiring to top of center console and re-install console. Close center console door, and if equipped with manual transmission, thread shifter knob back onto shifter.
  62. Carefully reinstall passenger airbag assembly and bolt into position. Reconnect passenger airbag wiring.
  63. Squeeze sides of glove box together, and close glove box.
  64. Remainder of re-assembly is the reverse of steps 14-8. Do not reinstall negative terminal as in step 7 yet.
  65. Final SRS Repower and Testing:

  66. Turn ignition switch to "on" position (do not start vehicle).
  67. Re-install fuse #31 in the SJB and put covers back on kick panel.
  68. .

  69. While insuring nobody is inside the vehicle, and everything clear of the airbags, reconnect battery ground and tighten terminal.
  70. Turn key back to "off" position, wait ten seconds, and then turn key back to "on" (not start) position. Watch the air bag indicator light. If everything is working correctly, the light will stay lit for approximately six seconds, then turn off. If the light does not turn on at all, stays on constantly, or flashes a code after initially staying on continuously for about 30 seconds, there is an unresolved SRS issue that needs to be resolved. Consult a dealer or certified automotive repair facility to diagnose and resolve fault.

Completed Installation shown above.

Note: The lettering on the button itself is pad-printed (paint stamped). The use of gentle cotton towels moistened with a small amount of water are all that is required to clean the button, should it become necessary. The use of harsh cleaners or abrasive paper towels is not recommend, and can damage the visual appearance of the button as testing has shown.
