1-5-3-6-2-4
Firing sequence is as follows 1 5 3 6 2 4 Distributor rotates clockwise
The wire sequence on the distributor cap just goes 1 thru 6, clockwise, starting from the number one position (which should be marked either on the cap or distributor).

If you are facing the distributor cap from the passenger side, starting at nearest to the front of the truck and going clockwise the sequence is 1-3-4-2. The timing check page below illustrates this.
1 - 5 - 3 - 6 - 2 - 4 The distributor rotor turns CLOCKWISE
look on the manifold it should have the squence engraved on it
Not sure what you mean by sequence. The harness does have a proper routing location and it must be plugged into the proper locations.
1, 2, 4, 3
1342 ( and the distributor rotor turns CLOCKWISE )
1 - 4 - 3 - 2
Look on top of the intake manifold for the firing order. Then make sure they are in the right order at the distributor.
