PCM keyed hot wire?

[91c1500sleeper]

Anyone know off hand what color wire to the PCM is the keyed 12V wire? The truck is carb'd and the PCM was removed 4 years ago when I installed the fitech. I need a keyed hot source for the electric choke on my edelbrock.

Are you running this to a relay or anything? The choke can actually pull a bit of Amperage. In past guys would pull it from the distributor and then theyd have issues with the truck running. If you are using the PCM wire as just a trigger for a relay you will be set. Another trigger you can use is there is a yellow wire that goes to the Windshield wipers as well.

I found the actual ecm 12 v keyed wire in the plug. Pink with a black stripe. Works like a champ.
