Is there a definitive list of everything the electronic portion of the
ignition switch covers?

Mine is defective - as the a/c, radio and speedometer work only
sometimes. I ordered a used one on eBay which corrected the a/c, radio
and speedometer - but was defective for the fuel pump -- wouldn't start
without an ether injection.

So I put the old one BACK in until I can get a new one next week.

I just want to be sure that this faulty ignition switch isn't
controlling anything to do with timing - as you might have read in all
of my other posts about timing belts and loss of power in my car.

Thanks.
