2003 impala door locks

I recently installed a keyless/entry alarm. Everything is working fine except for my brake lights and turn signal. I know that I have to diode isolateto get them to work properly. The problem I am haveing now is that i keep hearing a relay click on and off aven if the car is competly off. I have know idea where it is coming from all i know is that what ever it is causing my battery light to come on and go off for a split second which also causes the reverse lights to flash. I am going to diode isolate to see what happens any suggestiions.L67 Master (GM 3.8 SC)

Ummm sounds to me like your grabbed some wrong wires there buddy. The clicking noise is a relay triggering. I would post your install here. Copy paste your wire schematic and what keyless entry system you installed and what wire you connected to where."dont ground out!"

I second the "wrong wire" explanation. There should only be 3 wires on that car which need diode isolated IIRC - the door triggers and the (-) parking light flash(needs isolated from the BCM).C Renner's Auto Electronix

My service is cheap, quick, and good - pick any two

You can get a Blue wire at the  switch that will do (-) Pk Lights, no relays needed.
