Not to hijack the thread but I have a Icelink hissing noise question. You previously sent a great diagram of fixing the issue but in the diagram it show only 3 color wires...red, black and white I believe. Simple fix by relocating the black wire but here is the knocker. I check my Icelink harness and it has 4 wires so I left it alone. The hissing noise is there still is there a fix for this as well?
