High rev problem

[jondee86]

Impossible to say what has happened without knowing where those
two B-R wires go ? From memory, most of the blue wires are for things
like the wipers and washer, and one of the B-R wires should be a power
supply from near the underhood fuse box.

I don't even know how/why your idle should go high ? Usually it takes
extra air into the intake manifold to push the idle up ? Whatever, I would
get that switch out of there, as you don't know what it is interfering with.
If you want to install a cutoff, most alarm systems install a relay in the
power supply to the coil/igniter.

Then try and find out what is pushing the idle up, and work backwards
from there. Check every fuse you can find, every relay, see if the
engine check light is showing any fault codes, and maybe see if you
can find a spare ECU for testing. Good luck !!
