where abouts is the big multipulg connector? down by the ecu plug in the footwell?

anway when you take out the old loow in the footwell you will have 2 multi plugs, just connect colour for colour, green for the revcounter, black will be a switched live, fuel pump will be red/blue wire and temp signal will be blue wire, find these in the plugs and connect like for like, i fitted a mbe loom to dave bs mk3 at the weekend and was so easy.

just out of interest, was the engine out of a purple vectra as its sounds familiar

nope not out a purple vectra iw as out a astra sport with only the tb's,cams and flywheel

the rest is what im adding to it.

i know i have to remove the engine loom that gose to the ecu.
the starting/chargeing loom stays in.

i dont know where the conecter is on my astra thats one of the thinks im trying to find out looking at the tb loom it looks like the pulgs under the bonnet

got the fitting instructions direct from alpha/weber and they only do them for the vectra he said i would have to adaped them for my astra

there should only be a few wire that need connectig though, you should have::

permant 12v feed straigt to battery
switched 12v feed
earth usally by the ecu
tacho feed
fuel pump feed

and that should be it
