I disconnected the security module the other day and my speedo was erratic like a metronome. I unhooked my turbo timer and it fixed the problem but my headlghts won't turn on. All fuses are ok and relays look fine. It's not my ballasts, as I plugged in an old haloge on and it still wouldn't light... Also, when I'm in reverse, my ABS light now comes on. I'm puzzled..

Did you tap into the headlight power part of the harness to power the turbo timer? If you broke the connection somewhere check that area first or you may have shorted something. When you flip the lights, does it click under the glove box?

I'll double check. I do hear it click, I hear my ballast click too, so I know it's getting some power.
