Grounded blue connector, now car misfiring

[res7bequ]

Well I just went outside and was gonna adjust the timing on my 95 GST with a 6 bolt swap and I ended up grounding the wrong connector. Instead of grounding the brown one I got the blue one( I think its for a tacho or something) well now my Tachometer reads close to 0 at idle and car sounds like a subaru. What do you guys think I fried? coil pack/ecu... man this sucks I just spent my whole three day weekend working on car and now this shall pay more attention to everything.
thanks in advance, -Elias

First check all the fuses,disconnect battery maight have just freaked out the ecu. from there power transistor,coil pack etc.

Just checked and the two plugs on the coil pack on the passenger side aren't giving spark. Would replacing the coil pack fix it or do you guys think the problem might be elsewhere?

It could, but i wouldnt rule out the power transistor.Seeing how the tach isnt working like it should and the tac signal is in the P/T.

Just fixed it. Replaced the coil pack(which had sort of melted) and the power transistor just to make sure but yea... idles like a champ thanks 9 T. Having a cache of extra parts does come in handy remember you ground BROWN but blue.

No problem,I know what you mean about the spare parts I could probably start my own 1g part store.
