I have a 2010 SR5 DC. I put heaters in the seats, switches in the dash, but I have no idea where to tap into power for them. I do not have a manual so I don't know what the numbered connectors are or where they are located. I had a traumatic brain injury less than two years ago and my cognitive abilities now suck. I used to be an expert on automotive electrics but I look under the dash now and have no idea what I am looking at. Would someone please be so kind as to tell me where to hook into a switched source that will handle heated seats and exactly where to find it? Is there already a connector for heated seats in there somewhere? If so, where might that be and how can it be identified? Yes, I am basically asking you to hold my hand and guide me step by step while I do this. I apologize. You can't imagine how bad it makes me feel to ask for help like this but I really have no choice now.
