Maybe I wasn't looking hard enough, but I was under it, over it, in it, checking absolutely everywhere, bumper and lights off, checked chasis legs, but nothing.
The only things I found were stuff like the air temp sensor behind the rad and stuff.
But someone else with a 2003 mk1.5 focus 1.6 lx same as mine couldn't find them either.
Maybe they all used the same loom on the 1.4 and 1.6, and a different one on the 1.8 & 2.0?

I genuinely don't think they are there on the 1.6lx.

Someone prove me wrong!
