TBI 350 This motor is in a 1956 chevy truck.
I can't find the wire to unplug to set the timing.
where does this wire start from, and where does it go?

Thanks

Tan with a black stripe. Starts at the ignition control module goes to the ecm.

Thanks I found it.
So, I warm the motor up, then unplug it and set the timing to 0?
Thanks again
I'm a bit old school, so bare with me.

I been doing lot's of work on this truck.
I put a new fuel pump in the tank and found out it was wired wrong.
After putting the new fuel pump on, I when to hook up the battery and I heard air coming from the throttle body with the key OFF.
