Gl-boost Posted April 4, 2006 Share Posted April 4, 2006 I have an 87 GL-10 turbo, automatic 4WD. Yesterday while driving the car the check engine light came on, it used to do this before and go on and off so I never really botherd. Well It is now on and sometimes when I am of the gas and coasting, or when I am at a low rpm while driveing I can hear a knocking soung. It used to do this before also when the CEL used to blink on and off while driveing but would go away, It still does it but more than before. Didn't do it when driveing home from work tonight but it did this morning. So I have the problem of finding the diognostics connectors, I have read that they are white and green and under the hood by the wiper motor, well I have four plugs and none of which they seem to go into. I have two rectangle ones brown, and other black. The others are white round, and black round. not one gan plug into eachother. So a picture will help:confused: I now the led is under thedash but I just cant find the plugs. So can I please get help and please don't give me crap on searching, I have looked and not found much to my advantage, I just have to fix the car becasue I drive it everday and am really dependant on it.

BlueSteel Posted April 4, 2006 Share Posted April 4, 2006 on mine they were under the dash, near the ecu mounted under the steering column there should be a bright green male and female spade and a black male and female spade the green ones should be easy enough to find and the other will be right next to it good luck! *edit - should all be single wire plugs Link to comment Share on other sites More sharing options...
