switched 12v power source
Trying to finish ignition box install for my aftermarket ECU, but I'm having a hard time finding a second switched 12v source in the engine bay. I've seen a few threads saying to use the pink wire on the windshield wiper harness from the C3 guys but not much from the C4 guys other than the "Brown" wire under the dash. Can anyone help set me on the right direction.
Thanks
Thanks

If you still plan to run the HEI and the ignition box is just a booster to the HEI then I would look for another switched wire since it nay be too noisy,

I assumed you were using it for an ignition box, if that is the case it should be fine. People will tell you to stay away from that wire since it is noisy when it is running the HEI, but since you are eliminating the HEI with an ignition box it should be fine.

pnk/blk at the ESC knock amplifier on the side of the HVAC suitcase is hot in RUN and START, ECM IGN fuse 3 Amp.
pnk/ blk at canister purge solenoid (under LF headlight), or overdrive relay (near wiper motor) hot in RUN or START, GAUGES fuse 10 Amp.
pnk/blk at any injector, hot in RUN or START, INJ 1 fuse (left bank) INJ 2 (right bank) fuse.
The cruise servo does not have a power lead that is hot in RUN. Either does the Wiper motor in an 85.
