Where to hook up my Pink 12V wire for Sniper?

[fairlaniac]

I thought the stud on the back of my stock '66 Fairlane ignition switch was a good place. Evidently not. Where is a good place to hook up the pink wire on relatively stock wiring?

Thanks,

If stable voltage is important, then always right at the battery terminal.  You can use other sources, but you need to do a voltage drop test before tapping.  It's also good of you can put an oscilloscope on the source to verify stable voltage.

Not sure of the requirements but you could do like mentioned and go straight to battery, but use a relay and keyed power to operate it. Gets you straight voltage and easy off and on.

Pink is switched B+ right?

Caveat is it needs to be B+ in start and run positons.

Just don’t confuse the pink wire with the brown wire.....

Tasteless joke there somewhere....

I think voltage on that wire is far less important than you think it is.

All it needs to be switched on and off most EFI systems have a dedicated feed from the battery, that small wire is usually a trigger wire for other circuits that are on electronics relays within the ECM. My gut tells me you could even hook it to the coil feed and it would be happy during crank and run

I was thinking the same thing.  Worst case, you could use a small relay off the coil feed, in case the EFI wanted 12V but the pink resistor wire was still in play.
