Default Anyone have a wiring diagram?

Wanting to eliminate the in-car harness... Everything in the car is switched
and relayed to external pumps/fans. Basically an all-out race car running through a '99 PCM w/ HPT. I want to get rid of all of the wiring I don't need
anymore to clean things up; looking for a wiring diagram to make sure all of my I's are dotted before I rip everything out. Anybody have one?

Dude, I appreciate it. If you can post what you found, that would be killer.
I'm pretty much looking for all BCM-related wiring, as the PCM is already
set up correctly. Thanks again!

That's a big help to get started. Thanks a ton. I knew
that 95% of the wiring wasn't needed, but figuring out
the 2 or 3 wires I'll need to jumper or direct line is
the hurdle. This will get me most of the way there.

After I get this done, it's back to the dyno. I want to see 1000whp
with a strong and clean power curve. Pulling any power drains from
the system won't hurt...

Either buy or rework your existing engine harness to a stand alone unit so it runs with a single 12v switched input. The dash and rear harness should be replaced with a classic hotrod harness. Just enough to run the essentials and nothing else

You will be pulling your hair out trimming the stock dash harness down

The engine harness & PCM is going to be replaced by BS3 or Motec
before Bonneville next year, but I want to get what I can out of the
way for now. I'm not screwing around with anything forward of the
firewall; mainly hard-wiring all the 12v stuff... Just needed to know
which wires those were.
