    Hi Jimbo,

    Apart from the obvious earth strap from the engine to the front cross member,

    There is a vital earth that connects to the inlet manifold brown wire with washer fitting, near the right hand side, hose connectors

    nah the turbo model doesnt have an earth strap

    the only Astra G to have one was the 1.8 for some reason


    If in doubt you can fit your own from the block to the chassis, from battery neg to chassis, gearbox to chassis, alt to battery, and maybe the power from alt to battery too

    then theres the earth mod which is always good to do...

    Its always worth slapping on a couple of extra earth straps from the engine and ancillarys to the body, its surprising what problems can be avoided this way.

    I couldn't agree more,

    The reason why i put an earth strap from my z20leh engine to the slam panel was,

    Because whilst messing as one does i held, what i believe, and pretty sure of was an engine loom loose earth washer connecting wire,
    Hoping to connect up,
    but when i got hold of it , I hit the garage roof lol,
    That charge unharnessed could well ignite something
