me get an attitude lol the resistor looks like its been moved going by you very nice pictures but if there was no resistor then you could buy it from Maplins or what ever store you use over there for electrical things,
the tool used to fix the wire on is an electrical discharge similar to spot welding so the heat doesn't transfer to the resistor which will quickly bugger it up

edit: my apple I just noticed the 2 maf sensors are different[:-]
