Hey guys really need some answers don’t know what to do at all. But, I have a 2006 G35 coupe and I been wanting to put on my third brake light for the spoiler that I have instead of the rear window but when I finally got my third brake light to work I was just on park and nothing was happening so I thought everything was good so I went for a drive and right when I was starting to accelerate my “VDC off” & my “SLIP” light came on and it goes away once I turn the car on again and I do the same thing with a test drive and it comes up again...can someone help me please thanks

Well this problem with those lights coming on is that it’s never come on before until I messed with my third brake light wires and my brake fluid is good
