I just brought a universal O2 sensor and need to solder it up to the stock O2 clip. There's 4 wires and both match each other except for one. On the Denso Universal O2 there's 2 black,1white,1blue. And on the Stock O2 sensor there's 2 black,1white,1green. So do I just solder the Green and Blue wire together even it not color match?
