Hello Les Harrison,
That depends entirely on
HOW it WAS INSTALLED
and what you want to do NEXT.
Free (USA market) circuit drawings are available at
BBB Industries website (registration is required
(these are typically real FACTORY drawings))...
BBB Industries Premium Alternators Starters Power Steering Products
My best recommendation would be to find the INSTALL
directions...
I highly recommend CRUTCHFIELD as a premiere
supplier and TECHNICAL support for all automotive
entertainment, security & video issues (take a look)
Shop Car Stereos
Live technical support is available... but VERY LITTLE can be considered WITHOUT your
YEAR, MAKE & Model...
The real answer... VERY CAREFULLY: Take lots
of pictures, tag every wire... and strongly consider
purchasing a wire TONE TRACER.
If you just
cut it out... you will be needing a good
portable noise (radio or music maker (like iPod)).
They cannot read minds... Good luck.
