To start out, I have been doing tons of research and reading everything. The only thing that has me worried is the electrical part of it (CC,WTS,Throttle Pedal(maybe?)) I already have my donor and my suburban. The donor is a 2005 LLY basically without a body, but I have a cluster, 4x4 switch, and about every other part I could need from other part outs. Suburban is a 3/4 ton. If somebody could answer my questions that I'm a little confused about that would be great.

1. Does anybody have the schematics for what I have to do to make the cruise work, and what wires/connectors I have to use.

2. Where does the wait to start light come from/go to?

3. Since my suburban is 2005, I believe it is DBW, so the pedal is electric already. Will it work or will I have to switch that?

4. Transfer case control module, where's it located, and does it need to be switched for 4wd to work?

If somebody can point me in the direction for wiring schematics for the CC and WTS that I could purchase or view online, that would be great as well. I appreciate all of the help. I believe I have everything else figured out. Those are the topics that seem to be vaguely covered on conversions that I've read up on. I might just be worrying myself a little more than I should be. TIA

I did an lbz into an 03 3/4 ton sub I believe the sub is a drive by wire so no mods needed unless that is one of the ones I swapped in the C100 connector been several years ago. Accelerator swapped right over. The wait to start I just wired from the c100 to the cluster I believe. My suggestion is to get an alldata subscription for both vehicles transfer case module is under the steering wheel to the left side

Just saw this. Thanks for the info. After a lot of research I have figured a lot of it out. What did you do with your dual tank setup to flow between and filler neck to make it fit diesel nozzle?
