so I jus bought my wrx and it had a boost gauge installed, I went to install my double din navi unit I got and now the gauge no longer works...there are a couple loose wires that are jus chillen there that I think came undone wen I was pulling out the stock headunit...so i guess my question is..where do the 4 or so wires attached to...there is a white and black and then i think 3 other colored ones....thanks in advance
