Hi Scotts,

Thank you so much for your reply.

But im puzzle about another thing. If referring to the cruise control switch schematic, turning cruise control ON-OFF will short ECM Pin40 12V to ground. Will I then damage my ECM by doing this since it is outputing a 12V? And ECM Pin40 is an input or output port?

Thanks!
