The swap is pretty simple. Don't over analyze it folks!

Any questions regarding 00' 4.3l, to 03' 5.3l DBW SWAP. Feel free to ask. For now. I'm looking for any help regarding swapping the 00' I/P to 03' I/P. The PCM is 03', the BCM is factory (00' sierra...

VATS will get you no start! The 99 4.8 PCM still thinks it's in the same vehicle but with some random voltage from the key trying to make it pass. Even with relearn a million times over done...

Does your cluster have a digital odometer or analog? Do you have a message center? Is it working?

K1500, 2500 or C1500 2500? Original motor?

Here's what may be going on. 03+ PCMs on these motors sent more instrument panel info via serial data circuits. 02 prior used individual dedicated circuits, which means your BCM and instrument panel...

Project finished! Any questions regarding this feel free to ask.

Checkout workshop manuals.com for pinouts.

Look more into the I/P plugs under the hood, they are the C100 and C152. Those plugs ultimately control what info goes from motor and PCM to instrument panel.

What year motor did you swap in?

03+ oil pres sen all 3 circuits went straight to PCM, the PCM sent info through serial data.

I'll check out tomorrow. Ya 03+ had 3 circuits; a tan/wht pres sen sig, blk low ref, and grey +5v. 02 prior had a tan/wht circuit straight to I/P via C100 plug. What about inline 5v to 12v conversion?

I already spliced into that circuit and created a dedicated ground. I'll always report back. This is all about learning from other people's posted experiences, unfortunately most people find an...

Took the blk/wht ground pin#4 from the DP, grounded it, I/P lit right up! I'm still concerned why I have to ground off the DP.

So the good news, I sent PCM out for reflash and removed VATS. Plugged it back in vehicle started right up runs like a champ. I'll check the grounds in the AM and report bank ASAP. Thanks for help it...

Check the C2 fuse block under the hood inside fuse/electrical center, there youll find starter relay its labeled on the fuse center lid, turn the fuse block assembly over. its the middle rectangular...

5.3! Very little to wake the motor up. Small cam tune, good exhaust you can easily get 360rwhp through a 60e with minimal mods if any. You go to a 6.0 you may have to switch to an 80e. I know a lot...

Thanks!

Thanks bud! It's paint, DuPont Hot Rod Black. I was looking at wraps not too long ago. That stuff is crazy tjoE you can add any color or graphic you want. Like all the exotic cars Gumball 3000.

It's taken quite a few years, but she's almost done.

Hows everyone doing? I have yet to check in. I'm Rick, I've actually been visiting this site for some time. I'm the sole owner of 2000 GMC Sierra (ever). I've kept her for over 15 years because shes...

00' 4.3 to 03' 5.3. All plugs (C2, C100, C152) are pinned to schematic. Key in on position, I/P blank except MIL light. Key in on position with scan tool inserted into DP, I/P lights up like normal...

Here's the thing, 4.8s came with a 4L60-E all across the board. A ton 6.0 motors came with a 4L80-E, HD flex plate I believe (128 teeth).and those came with oil coolers. A ton of 6.0s were used with...

Hey there sorry in advance for the lengthy reply. Everything on the C2, C100, and C152 are repinned 100% to schematic. Here's the problem. Motor turns, starts, then stalls I'm thinking VATS cause...

Looking for a descriptive pinout for the c2 block. I have the std pinout diagrams, they describe most of the circuits, but they only describe a few out of the 23 pink ign 1 volt circuits (I.e: MAF,...
