Electric choke wire

Wondering on a painless harness. Is the electric choke wire #954 12v on crank and ignition on? The books lists it as "B+". I am running the Holley sniper and it requires you connect the pink wire to a 12v key'd wire that is hot in crank and run.

In a stock harness you would not be able to use the White w/black stripe choke wire. It's only powered up when the engine is running (gets it's power from the alternator stator windings) and isn't even a full 12v all the time anyway. Probably not good for your Sniper.

But with Painless, I'm not sure.
The only single wires that are normally guaranteed to be hot in both positions are the Green w/red and the Red w/green wires on a stock directly from the ignition switch. This is done in the ignition switch itself.
You can also fake that function with 2 wires by using the starter relay's Brown "I" wire to get your START signal. And then any other wire hot in RUN.

The Green one is for the voltage regulator and the Red one is for the ignition coil.
The Painless harness "might" have the White choke wire hot in both, but you might want to PM Eric at Painless (erico01 here on the forum) to see if he's got a quick answer for you.
Or just check it? Easy to do with a volt-meter or light. You know it's hot with the key on, so have someone hold the key in START while you test.

The function of the Painless harness is very similar to stock, but the way they achieve some functional details are different for some of the circuits.

Sorry I haven't read the Painless manual in depth lately, so can't answer more specifically about the other wires in their system. Especially all the extra wires at your disposal.
But test the White choke wire (White w/black stripe?) before deciding to utilize it.
