Peter_H,
If you are trying to keep your truck COMPLETELY as it came from the factory then I would suggest the cloth covered wiring. Much more expensive. If not, the high temperature vinyl will work. Much less expensive. Most of the cloth covered wiring harnesses today have the high temp vinyl under the cloth sheath.
Hope this helps.
Tim
