Normally the van transmissions are the 2 wheel drive versions (they have both the turbine-shaft speed sensor and output speed sensor).
Most of the tucks have the 4 wheel drive version of the transmission (they will not have an output speed sensor and wiring).
Some of these transmissions do not even have a reluctor for the output speed sensor (you do not want to use that type of transmission in a 2 wheel drive vehicle).
Unless you want to take wiring from the transfer case area of the truck (output speed sensor circuits)...
And add it into the 4 wheel drive transmission wiring...
Then you are better off just purchasing some connector pig-tails to replace the wiring sections/ connectors that got damaged by your friend.
If the Truck is 2 wheel drive, then you should be fine.
It is best not to take on a repair that a person is not familiar with.
Improper electrical wiring can be unsafe to the installer and for the operator of the vehicle in the right circumstances.
Fortunately, the circuits being repaired in this case do not really pose much danger, however electrical repair can be unsafe in general.
Best be safe and pay for this relatively inexpensive repair, should this not be a repair you are familiar with.

I TOOK PICS OF HARNESS AND HAVE A CUT WIRE ON THE 20 PIN PLUG "GRAY' RED/BLK PRESSURE CONTROL (PC) SOLENOID VALVE CONTROLLED POWER
DO I NEED THAT???
AND THE OTHER PLUG HAS 3 WIRES CUTS ON THE Neutral Safety Switch 2 DK GRN AND A GRN
DO I NEED TO HOOK THAP PLUG UP DONT CARE FOR Neutral Safety Switch??
AND FOR THE SPEEDO WHAT WOULD I USE ??

Yes, all of those wires should be connected regardless.
The speedometer originally operated off of the output speed sensor/ circuit.
Did you read what I posted above about 4 wheel drive versions of the transmission?
