I'm installing a turbo timer on my car and right now and I got the contant 12volt and ignition 12volts hooked up. But, I'm having trouble finding the ignition #2. Without it, the engine shuts off after I turn the key off and only the accesories would be running.
I'm using this site

to figure out which wires which. And according to that page, ignition #2 is on the ignition harness? I'm having a really big trouble trying to figure out where this ignition harness is. I'm looking under the steering wheel and I see bunch of wires coming out from the steering column. I know some are for blinkers, brights windshield wipers, etc. So, I dont want to cut into a random harness. Which harness is it exactly?
