Question on American AutoWire Update kit

[gfreeze1025]

So I am about to start on the Wire upgrade kit but I was wondering if I can do the inside cab first and still use the OEM wiring kit for everything under the hood.

Reason is that my Blazer is a daily driver, and I'd like to do it in stages to reduce down time.

Plan is to do the work in the cab in a day or two then finish up with all the outside stuff.
