the diagnostic plug is numbered see this....http://www.volvospeed.com/CheckEngine.php

i think iget what u mean im just still on with finding the plug the wires from the ecu are ready ,i put the plug that safe i carnt find it yet lol

yes find the plug if you can....have you got the cable but no plug?......what happens theoretically is when you push the button with the plug in it sends a + pulse to the ecu...in return the ecu send a - pulse back, the + is deffo thro the flylead but whether the ecu - comes back thro it i dont know...i have thought of a bypass tho if this does not work ....
keep working till the early hours andy
all the very best

right jod after moveing a few garder weeds ive found it,
has A black socket
and B socket in grey
which both sockets are numberd
unsure why there is no number 4 but never mind
some of the plug wires have numbers 2
do both plugs have to be wired up or just the black A plug has that has a led on it?(hope im not ben 2 confuseing here


and the ecu numbers are same on both sides of the ecu?

right jod im just off in the bug to wire the 3 wires up
8 earth
4 (redlight to yellow violet to matching wire on ecu
2 yellow brown to matching ecu wire
then do i turn the igition on and if anything flashers (back in 10 lol wireing its stressfull im sound at mofying stuff lol

right jod a small prob the number 4 (red light wire carnt find a matching wire on the ecu?

right jod the redlight wire 4 is contected to another spare wire what was in the loom not the ecu as its the same colour of wire,
so ive got the 3 wires contected and removed the cover of the plug and nothing has happerned do i now get the black wire on the plug socket and plug it into a number ?
