wiring for race car

OH NO/ not another one ! lol

There’s always one.... lol

But to the OP tell us more information.
Is your battery mounted in the trunk?
Do you have a battery cut off switch?
Are you running relays for your electric fuel pump, if so equipped?
There are several ways to to wire a car, using a relay close to the fuel pump can provide full voltage while using a switch to make and break the relays coil, letting the relay take care of a high amp load.
Are you running N2o? A WOT switch should be switching a relay that in turn will be sending power to your nitrous solenoids...
A properly wired battery disconnect switch will de energize the car and the charging/ ignition system.....
What’s your electrical abilities and experience?
MSD has easy to follow wiring diagrams.
Is this a total rewire or are you just looking to add to your existing wiring harness?
