I am replacing a wake plate gauge in a 2005 supra launch 22ssv. My old gauge wiring has 5 post, one with yellow wire, one blue, one post with 2 black, and one with a purple and red. The new gauge has a wiring harness with 2 black, 2 green, one purple and one blue. I would assume 2 black to 2 black and blue to blue put I am not sure what to do with the others. Any ideas?
