What are the three unused connectors for on the back of an 86110-47230 in a 2009? Looking at the back, at the top, to the left of the two long connectors. Right to left there's a square, white connector, a square, blue connector, and down in a hole is a tiny, white connector. About to send it off to AutoBeYours to get repaired from its intermittent turning off, freezing, and fading to white.
