where is the oil preshure sender on a dx engine??

hi just trying to find out where it is but my haynes doesnt say! can anyone help me, also a pic would be great! many thanks, rob  

i have one of the side of the cylinder head. it is a cylinder shape too actually. Not the brown wire with the blue bit, but the other one going onto the side. It is the one that my VDO uses. Like this one… (disclaimer: not my engine!)



there is also one on top of the oil filter housing. This one is for my MFA. like this one…
