Hi, can someone who knows the 6 speed boxes really well please advise on something.

im doing a box swap soon and am looking at the possibility of adding gearbox and diff temp sensors. The diff temp sensor will be relatively easy, but im unsure where the best place would be to tap into the oil system circulating in the box! And if temps do look a bit high on track, i might even think about using this tap into the box to feed a cooler.

first things fir=st though, where to put the sensor?

 

anybody?
