Hello. I would look on the inside nearthe parking brake and make sure the lower harness is tight against the outside of the firewall. There our two harnesses coming in from that location through the firewall make sure there tight. If in question pull the carpet back and pull the lower plug out the outer clip on the firewall side will hold the outside in place while you can pull the lower plug from inside. Might want to spray some electronoc cleaner on the male and female plugs as I did. Larry.
