Wiring Undercarriage lights

[shadowkenobi]

does anyone know how to wire the lights at the (upbum) bottom of the car to only come on when you unlock your car? cause i figure if the headlights can do that then i should be able to do the undercarriage lights.

by coming on i mean flash when you unlock

They'd probably have to be LEDs, as neons need more than a second or so to light up.

aftermarket alarm or OEM keyless?

OEM Keyless

should be able to tap into a relay im sure!

The OEM keyless uses the hazards, so you can either tap into the hazards wire at the hazard switch or at the OEM keyless module.

use a relay, get the power wire that flashes the lights, have the switch wire for the leds inline on the relay,when the relay is energized from the hazzard wire, the leds will turn on

 

[Solo2Protege]

the hazard wire is green/orange (negative trigger) and is located either at the switch on the dash or at the OEM keyless module.

relay wiring option: (If no switch is used, just connect the hazard wire to the relay without diodes)

pin 87 = 12volt fused 7.5amp (use same connection and *Y* the wire to also feed the switch)
pin 87a = not used
pin 86 = switched chassis ground from switch AND hazard wire (diode isolate at relay connection)
pin 85 = 12volt + (use same 12volt from main connection by using a jumper on the relay)
pin 30 = 12volt output to LEDs

Since the hazard wire is a negative, use the ground from the switch and power it with the same 12volt power used for the relay, be sure both the relay and switch are on the FUSED side.

i.e. connect 1 wire to 12v power in car with a fuse holder, THEN connect 2 wires to the fuse holder lead and feed the relay and the switch. But before you connect the main 12v power to pin 87 of the relay, add another 2" peice of wire and jump it over to pin 85.

EDIT: forgot i hada scanner at work...lol anyway, maybe this will help to make more sense.
