12 volt constant source?

[Erik Beckett]

I am installing the Atomic EFI and they require a power wire to the battery that is constant 12. First Gen Camaros have a stud by the battery thst is 12 volts and also the horn relay is 12 volts constant , can I connect the wire to one of these?



Thanks, Erik

Yes. You can also connect them at the starter terminal, or even at the back of the alternator.

We do a few EFI installs and troubleshooting. 99% of the time we see wiring issues. I'd recommend going to the battery to eliminate variables in system voltage. Connecting to anything on the engine puts the engine grounds in play for voltage drops, and for any other source other than the battery for that matter. You'll make any troubleshooting problems later easier by connecting directly to the battery.
