g'day,

does anyone know of where the au3 xr6 cluster picks up the inputs for the tacho and temp senders?? got a hold of the au2 books but it seems to be the wrong diagrams, i say this as most of the colours dont match up behind the dash... mainly i need to hook up the original tacho to an msd 6al, not sure if you can but it would be nice as a aftermarket one will look a bit crap i feel, also the books dont say anything about a high temp light switch or gauge sender, is this a derived value from the computer??? can these thing really be this smart???

Yep, only one temp sensor on an AU motor and its in the back of the head.

that one thats about 2 1/2 inches long???? tried heating it up but nothing.... it was earthed and everything! this microprocessor is far to smart for my liking!!!!

yeah there different alright!, im using a au2 ford manual for info... the high series cluster drawings dont seem to match up with bugger all..... the closest one that sort of looks like it are a LWB low series cluster.... go figure.......
