I am installing an aftermarket alarm. When connected to my parking light brown wire in the dash, my turn signals and brake lights stopped working. I chked all fuses and replaced signal relay located under right side of steering column. Now I'm stumped. I have completely diconnected alarm system fixed all wiring as I began. No luck. Any ideas
