I have a misfire and am wondering if it is due to this wiring patch to the blackjax.
2009 Hatch impreza STi.

Got this anti hijack unit fitted by dealer.

2 wires taken off plug 3 coil pack loom.
GREY wire ( middle ) goes to a black wire ...
and
Yellow ( left, by release clip ) goes to a brown wire on blackjax.

One ( brown ) wire goes to the alarm sounder unit, the black one stops dead .. is not used.
(No idea what goes to the alarm module or from where!)

Question is - should the black wire ( from the coil pack middle grey wire ) go anywhere?

Is it interfering in normal spark etc. if a wire is missing a connection.

Continuity of wire to coil seems ok, and to the Clifford wires too.


Any ideas?

Cheers

 

Take it back to dealer

 

They went bust 15 months ago!

Out of warranty anyway, and I don't think they had the annual Clifford checks done anyway.
