nice post cr... i needed that a couple days ago... hahahha....first off check and make sure ur fuses arn't blown, then if u have a volt meter check ur constant power (yellow wire)and c if u have 12v, then ur acc (red wire)and c if u have 12v when the car is on... both of these us ur ground wire for ur ground or u can use ur key hole for the ground...

 

thanks yeah first thing i checked was the fuses but of course it wouldnt be that easy. im gonna go ahead and check on the volts tomorrow thanks
