Ignition wire colour?

[AJ_08]

Hello,

1987 Buick Grand National.

Does anyone know what the ignition wire colour is (12 volts power wire when cranking) ?

Thanks salvage. Just found a diagram, says purple or purple/wht. You know why the difference?

Are you looking for an ECM sw 12v that stays hot cranking? I use the factory one in the C437 plug the factory engine harness uses to plug into the dash harness. It is Pin F

No, was just looking for the ignition wire that gets 12 volts when the key is turned/cranked and sends a signal to the starter. But this is good information as well. Cheers.

I assumed this location for the "crank" wire. Same color with or without factory alarm system.
