12v Ignition Wire

[KrispyS10]

I just rewired my MSD Digital 7 in the truck (89S10) Before I could crank the truck with the key and turn it off with the key. Now for some reason I can't find a wire that is hot with the key on and hot while cranking. Im hooking the small 12v wire from the MSD to a switched source like it says but no luck. I believe there was a pink wire under the dash that hooks to the column then goes above with many other wires. I have got under the dash with the test light and have tried seems like every wire. Maybe someone can lead me in the right direction. Thanks Mike

Mike, There is a couple areas you can use. There is an ECM and ECMB fuses. Both are 10amp. The ECM fuse runs a Pink/White. The ECMB is an Orange. Both are hot in run and start.

The wire ya need is a big pink one.
