on the last week I noticed that I had ignited lamp "check engine".
I tried to find out what's the problem with in "clip". so, i'm open the cover near hand-brake, and saw

well, i have read that i should close contacts 5 and 6, but there weren't any contacts on the 6th connector. may be contact 6 - mean ground (minus), and i should make contact between 5 and ground ("-") with clip?
