thanks t5 stealth the info i have got is from the haynes manual for a v70 and these are the only two that are different to the ecu and wiring on the 850 t5.i was wondering if volvo had just changed the colours of the wiring for these two pins.

it might be difrent as the v70 probly uses difrent sytems etc...
ie throttle body is fly by wire but 850 is a cable ....that sort of thing

yes i made sure i looked at the wiring diagram for pre me7 because of that, i think the system for 850's and pre me7 are the same (motronic 4.3/4.4) but hopefully someone can confirm this.
