okay we putting in a tbi 350 for some one when put the distributor in do you have to unplug the timing advance/retard plug to set or not?

Yes..... unplugged for initial timing of 0⁰, then plug back in.

when put the distributor in do you have to unplug the timing advance/retard plug to set or not?

Yes, once the engine is warm, you disconnect the Blk/Gry EST (Electronic Spark Timing), start it up and set it to zero with the timing light. Shut it off, disconnect the negative battery cable and short it to the positive so, you reset the MALF code. Hook it back up (negative and EST Bypass Wire). Start it up and you're good to go.

What year truck? The wire is in different positions depending on year.

I watched these am under the impression that this need to be do every time the distributor is disturbed (removed installed)

The wire may be hidden in the big wire harness, you may have to dig it out. Here's what mine looks like om my 88
