1998 Blazer Auto to Manual swap

[notallthere]

So a buddy of mine has a 1998 Blazer with an automatic. He wants to swap over to a manual. He has another Blazer to pull from for the swap. I know the basics that the trans will swap over. The pedals and computer need to be changed out. Possibly the driveshafts, and cross member. Will any of the wiring need to be changed out? Has anyone done this to give some advice? My suggestion would be to safety the manual one and drive that but he did not like that suggestion.
