So I'm working on a 93 FD and ran into some trouble. The wire harness has been hacked and spliced sometimes in several spots. I pulled codes and got 3 errors. One was the thermosensor, one was for the knock sensor and I don't recall the last one. So I dug around the engine bay and found a few wires that were poorly connected (just two bare ends twisted together) so I used a good connector on them. This made the thermosensor and the 3rd error code go away. But left me with the knock sensor error and CEL. I need this guy to pass emissions like yesterday.

SO, what I've found from searching is that the power steering and the knock sensor share common plugs. But the knock sensor was hacked off. So I ended up taking that sensor off and replaced it with one I had laying around (S5 turbo) just to try it. I hooked it up to the bare wire (also hacked) in what seemed to be the right spot, plugged battery back in and checked for codes. Still there.

I was thinking that maybe the thermosensor wire was traded around in this mess because the wire is extended and I haven't seen the fans kick on yet. But when I swapped the thermosensor and the knock, I still had a CEL for the knock sensor.


I need to find out what sensor goes to what colored wire. I hear that the knock sensor goes to a black wire?

Thermosensor is currently hooked up to a brown wire with yellow stripe and blue dots
Power Steering is hooked to a blue wire w yellow stripe and red dots.

Only other wire is a black wire with red dots. At least as far as I can see.

Thanks for any help. It's late and this probably doesn't make a lot of sense. Sorry.
