Truck harness question

I started depinning yesterday went well just have a question about one wire coming of the C2 fuse block. Cut from the E2 position on the block said its for the transmission, pcm, but I cut it and its just there by itself. Think it went to either the c100 or c102 what do I do with it?

Re: Truck harness question

Also left r17 and r43 for ac controls I believe this is correct. Still have to go back and put the pins in for the dual fans

If you're talking about the wire I'm thinking of its the tranny power wire that, on the truck, routes through the truck fuse block first.
In addition to those connections, you need to connect C100 pin C, Pink, to 12v+ RUN/START source. This wire feeds the Transmission Solenoids and PCM. The fuse for this wire is NOT in the underhood fuse block. The fuse was located in the underdash fuseblock in the 99+ pickups. You need to use a 10A fuse for this wire and hook to a RUN/START 12v+ source. This wire runs from C100 Pin C to Underhood Fuseblock C2 - E2. Inside the fuse block, it turns around and comes back out on C2 - F2. F2 then runs to the PCM and Transmission.

If it is that wire, I'm pretty sure that you won't need to worry about that one. All you'd need is the run the wire that came from F2 to a fuse on whatever fuse block you're going to use. (That's what I'm doing).
But if i'm wrong, here is the website I've been using for my LS swap with truck harness:

Thanks man! I asked my wife's cousin he has just done a swap on his blazer so he cleared up a lot of questions.
