The cab year and the original engine family (I6, V6, or V8) would help. GM changed a bunch of wiring colors over the production run of these trucks.

Choke is LIGHT BLUE for most years.

The TACH wire is BROWN or WHITE depending on the year. That connector isn't right for the HEI TACH lead.

The kickdown engages passing gear when you floor it.
Your TH350 has a kickdown cable.
A TH400 uses an electric switch on the gas pedal. If it came with a TH400 there will be a switch next to the gas pedal in the cab.
