Hello, There are two components that look like the main relay. first one is behind the silver cruise control which seems a bit larger than what's pictured on the web page it's brown. The second one is located on a board with othercomponents it says MITSUBA/12.v8 3305 on it. looks like it's plugged in directly to the board. Which one is it? Also, the slow grinding probably is because the ignition timeing was advanced. I don't think it'll kick in if that wasen't the case. Many thanks, John
