I thought the drive by wire was going to be hard I'm so wrong that was the easiest part so far power ground and two serial data wires. I guess I'm teaching myself a lesson decided to make my own harness and so far it's not fun.I know that piece...
Yes I'm running the p59 PCM I'm using one out of a 05 Chevy avalanche (flex fuel) And I also using HP tuners. I am using a eBay swap harness as my base to start with since it's pretty much set up for passenger side installation. Only thing nice about it, It has most of the plugs I need but China really needs to pay those 8-year-old kids more to make them better more then half of the pins were wired wrong. Example the two front O2 sensors were wired to ignition power not to the PCM so the heaters would have been on all the time when the vehicle was running. Why it's such a pain for me on this is because I am tucking it along the firewall up by the original OEM harness give it a nice neat look instead of just stringing it behind the motor and adding all the sensors that are missing from that swap harness plus cleaning up the donor harness as I'm going along. I've been doing automotive wiring since 1988 in the car audio video security & GPS field. I guess I developed a little bit of OCD over the 30+ years making my wiring look OEM and blending to the vehicle like I was not even there.I would think on an 04 since your already wired for a P59 PCM (which is the same as an 0411 just a tad faster) that about all you'd need to do is rework your injector and coil wiring. All the other sensors are nearly the same. KS will need another wire. Just remove the old KS wiring. Might need to extend a few others. then have your PCM programmed for your engine. I had Brendan at lt1swap.com do mine. He was charging $75. He can add fans, and delete what you want.
Check out his website. LT1 Swap
I built my own for a 99. Those had the black box PCMs. It was a big project. I found I was referring to the 03-04 S10 wiring diagram a lot. If you use the LS harness to start with everything will be on the wrong side of the truck. I'm actually thinking of redoing mine by getting an 03-04 S10 harness to start with. To clean it up a bit.
I started out soldering all my splices, but about mid way I bought a pair of serious crimping pliers and crimped most of the rest of it. You need a pair of pliers where the crimp is done on the opposite side of the pivot as the handles. The old standby cutting, stripping crimping pliers don't get it. A bunch of good marine grade 3 to1 shrink wrap with the adhesive/sealant inside both weatherproofs the splice and strengthens it. About wore out my HF heat gun.
I'm not using the old cruise control I'm just plugging into the wiring. I found the mail side plug for I don't have to cut that one off. The four wires I need are in that plug.You don't use your old cruise control. Your remove it. The 4 wires from the column plug into the TAC and the DBW does the job of the Cruise control. I put the TAC where the CC was on the firewall. I did add a Metri-Pack 4 pin connector into the 4 wires on the engine side of the firewall so I could remove the TAC w/o unpinning those wires from TAC. The ends on them would have just snapped into the TAC because the terminals used on the TAC and old CC are the same style.
Ya, never keep track of what any mod costs or how long it takes . You'll only scare yourself and others from attempting or finishing any similar. Plus family members won't be kind either . Jus say not much and not long when axed.Update. 04/23/22
2004 Chevy Blazer Ls 2dr. I am putting a 5.3L (L59) from a 03 GMC Yukon drive by wire with 4L60E . So far have parts on order from current performance and Holly just waiting for them to come in so I can start fitting the 5.3 into the Blazer . With the summit racing Pistons Chevy performance head gaskets and 243 heads Mill down to 62 CC my compression will be 10.6.1 CR. Should work well with the 2004 LS6 Corvette camshaft I'm going to be using.

I'm not keeping track of how much I'm spending I know I said it somewhere in this thread it's better that way. Just looking forward to getting it done. But I'm glad I picked up these injectors because I'm going to be running e85. I know I won't run out of injectors on E85 and it will keep the injector duty cycle low.Ya, never keep track of what any mod costs or how long it takes .

Nice where did you get it?Just ordered a complete cathedral port Trailblazer SS intake manifold when it comes in a post some pictures.
That's what I did to my purge valve set up. I wanted that hose set up on yours but couldn't find it and didn't want to wait on it.I was bored so I decided to browse around good old eBay and found a complete TrailBlazer SS intake. Picked it up for $275 shipped.

I used a Dayco 71994 upper hose for 2000 Neon. I opted to not add any additional low end torque or hp and just kept the OE 2004m TB intake. A 250-300HP improvement over the stock 110 4-banger will be plenty.Here you go, purge valve hoes GM 12574897
What is the part number to your top radiator hose that you are using?
I decided to go with the trailblazer SS intake because I'm running the LS6 Corvette Cam with the 243 heads with the higher compression pistons. I saw a video put out by SDPC where they did a test between the standard truck intake and the trailblazer SS. The trailblazer SS had a gain of 20+ horsepower on a stock with cam LM4 5.3L.
I decided to use the LS6 Corvette Cam because it has less torque but excellent top end. With my blazer being such a short wheelbase some loss of torque would not really matter. That's why I wanted the trailblazer SS intake to help with the top end. Hoping to get everything done and running by March or April next year because I really want to do Rocky mountain race week. Not trying to win anything, just going to have some fun but I don't want to be the turtle at the track either.I used a Dayco 71994 upper hose for 2000 Neon.
