How do I add the afterburner effect for my SR-71?

Greetings-

I downloaded the Alphasim SR-71A add-on for FSX and even though it says it comes with the cool afterburner effect, I can't get it to work. Anyone here know how to config the afterburners to work?

Here's what my config is in the SR-71 airplane.cfg file:

[lights]

//Types: 1=beacon, 2=strobe, 3=navigation, 4=cockpit, 5=landing

light.0 = 1, 1.137, 0.4, 3.62, fx_beaconb ,
light.1 = 1, 2.9, 0, -2, fx_beaconb ,
light.2 = 4, 32.4, 0.00 , 2.85, fx_vclight

//afterburner effects
light.11= 6, -41.0, -15.50, 0.3, fx_F14_Burn1 , // Eng1 Afterburner Burn1
light.12= 6, -41.0, -15.50, 0.3, fx_F14_Burn2 , // Eng1 Afterburner Burn2
light.13= 6, -48.5, -15.50, 0.0, fx_F14_Burnerflame , // Eng1 Afterburner Flame
light.14= 7, -41.0, 15.50, 0.3, fx_F14_Burn1 , // Eng2 Afterburner Burn1
light.15= 7, -41.0, 15.50, 0.3, fx_F14_Burn2 , // Eng2 Afterburner Burn2
light.16= 7, -48.5, 15.50, 0.0, fx_F14_Burnerflame , // Eng2 Afterburner Flame
light.17= 6, -40.0, -15.50, 0.5, fx_F14_Blueflame , // Eng1 Blueflame,
light.18= 7, -40.0, 15.50, 0.5, fx_F14_Blueflame , // Eng2 Blueflame,

This is the effect I am looking for:

Any help is greatly appreciated!
