That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing. That's the fuel injectors. BUT, right behind the yellow plugs, are black ones. The black one is the connector to the spark plug. The plug itself sits about 4 inches down into the block of the engine. They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).

This is all electrical. Sounds like a fairly big job. Blinkers and ABS usually run from same fuse and therefore same wiring. Not sure of the 4x4 light. But Id say if you get a wiring diagram and folloe from the 3 items back there would be a common wore and id say in your case this wire is loose, or semi broken. However I think it would be less stress if you simply go to an auto electrician, Good luck, hope this helps.

i am not going to lie to you on this. if you do not have a very good mechanical back ground you should not attemp this procedure your self because it could result in serious injury. it should be brought to a shop because they do have the right tools to do this. alot of the time ball joints are pressed in under extream amounts of pressure

Testimonial: "hey thanks, but I guess the idle control valve I bought was faulty, so I took it back replaced it and the noise is gone. "
