Greetings everyone! I am new to this forum but not new to Dakota's. I am on my fourth truck with all of them being modified in some way. This new project is a 03 quad cab 4.7. I got the truck for cheap and the owner told me the engine was locked up. I got it home and put a new battery in and she fired right up! Steam out the exhaust let me know the head gasket was bad. I am not new to engine swaps or anything but i am new to the lsx platform. Anyway here's my goals... Swap 5.3 in with 4l60 for now. Flip manifolds for turbo. Wire into factory gauges if possible, or I was thinking of doing an I pad mini where the old cluster is and sending the info to that. Eventually swap in 4l80 or t56. All of my Dakotas have been manual and the only one that was not I swapped to manual. I would like to say thanks also for this website. After reasearching this for over a year I came up almost empty handed. People on other Dakota websites are very hostile to thinking outside the box. Anyway...hello and thanks! Kyle.

Hi Kyle.
We will not be hostile on this site. I really want to develop a place for real conversation about these trucks and their potential.
I see about 1/2 of these trucks being destroyed in the next few years as the aging drivetrains and high cost to repair leave situations like yours. I must see 8-10 Dakotas and Durangos at LKQ every month, with a 30 day sentence.
Too bad. I think these trucks look nice, the chassis is solid, and many still have nice interiors.
Love the Chevy TB. Did the TPS and IAC connect, or did you have to switch connector ends. I think at least one is the same.
Also, what area do you live in, looks like the south.

Most of my black truck was sourced from junkyards. Interior, trans, and various other parts all came from my local yard. The Chevy throttle body too. With the chevy throttle Body it drives like a new truck. Lots more top end power. I put the factory dodge iac in the Chevy throttle body, the Chevy one was pinned different. The wires had to be extended but The tps is the Chevy unit wired into my stock harness. My tps values are within .05 v of the dodge PCM limits. I'm at the limit of what the 5.9 can do without dumping tons of money into it. 14.2 on motor @96 spinning, and 13.2 @106 on a 100 shot. 2.0 60 foot. I got a 1.8 60 foot but then broke 3rd gear in My trans so never got that 12.9 run out of it. Id rather not undo a perfectly running truck to put a 5.3 in so i picked up this quad cab. I fugure i can make more power to make up for The extra weight pretty easy with a turbo. Im down in south Florida just north of West palm about 25 miles. It's a great area with killer fishing.

I also am on the hunt for an engine. I see gen 3 5.3s everywhere, but i also see gen 4 ones like the 07 LY5. I was thinking of using an I pad mini and Superchips I hawk for my gauge cluster. It says that I have to have a can enabled vehicle for that to work and most vehicles from 07 and up are. This is where the gen4 engine comes in. Im not sure how I can achieve this in a swap situation or if it works. It's just an idea. Also how's the wiring on a gen 4 compare to gen 3? I am doing my homework but can't find any info about this can network.

Can you post your videos again in a thread called LS1 throttle body on Magnum engine? If anybody cruises the website who still feels nostalgia for the magnum, I would like them to see this.
This is exactly what I am planning with my Kenne Bell blower and a modified blower assembly.
I live in Tampa.
Feel free to check my technical articles, I will be adding some soon.
Gauges. Not hard at all. Stock gauges work fine on any LS motor. You just have to remove the wiring for the 5v sensors, fuel injection, coil, etc so it doesn't draw down the ECU. I am planning on grabbing some harnesses from LKQ and modifying them for sale. But you seem pretty comfortable with wiring.
Wiring. Current performance in Hudson, FL did mine. Great job retainin original relays in power distribution block. I will take better pictures of it and post. At this time I could probably reverse-engineer the wiring, but LS engines are new to me, and the price he charged was worth the money.
I got my drivetrain from Ebay. It was Shawn from RetroLSX, but I think he has since gone out of business. Only tips I can speak to is get an entire assembly, engine, trans, pedal, ECU, TCU, wiring harness, AND EXHAUST FLANGES AND TRANSMISSION YOKE (I forgot to get these, it sucked) from one vehicle if possible. Physically putting the drivetrain in is easy.

Sure, Ill post a thread about the Chevy throttle body. I did one on Dakota durrango with mixed responses. As far as I know I'm the first one to do this on the magnum. I call it the wanna be Chevy under my hood. Hopefully soon it will be a real one. It's good to see a fellow Floridian. It's good to hear that my factory gauges can work too, but I have an 03. It uses a different system than 00 and older. I could always swap to a 00 gauge cluster I suppose. What exactly did current performance do for your truck? Despite the fact that I can do a little wiring, I still would rather have a plug and play option.

Despite the fact that I can do a little wiring, I still would rather have a plug and play option. I never understood why the dak/dur throttle body has 2 or 4 barrel openings like a carburetor. The fuel and timing is based on MAP/IAT. I had thought about this long ago, but ended up getting a ported/polished throttle body off ebay for like $75. Pretty good deal then. Despite the fact that the ECU has a different protocol, the process is still the same. Analog sensors (oil, coolant, voltmeter, fuel), are all converted to digital by the ECU and sent via the BUS to the cluster. On the older years, the speed comes off of a hall effect sensor on the ring gear. While I was in the middle of the swap, with the engine out, I checked the coolant temp by dipping it in hot water - worked. Connected the oil pressure sender to my air compressor - worked. Assumed at that point everything else would work. When the key is in the run position, the sensors are powered and the ECU transfers the signal. That is why, I assume, you can turn your car off after it is hot, key on and see the current temperature, volts, fuel level, etc. Jared tapped into the distribution block and used all of the relays to power everything (injectors, fuel pump, coils, etc.) and passed a wire for the Drive by wire pedal through the firewall. He said it was 19 connections. It took him 6 hours labor. He connected the harness with a couple of 12 pin weather connectors, so it is completely removable.

I will definatly have to get with jared on the wiring. So he combines the dodge harness and the new Chevy one and integrates both? I am also looking into this CAN bus system all the new cars use. Apparently it uses one and two wire signals to send alot of info. Multiple gauges etc. The Superchips I hawk uses the can bus to send a Bluetooth signal to a supported device such as I pad. I'm wondering if I can get an 07 engine and harness and retain the CAN system, and be able to use the I pad as my gauges. I think It would be pretty slick but seems to cost alot more because I need a gen 4 engine and harness and I don't know if it would be worth it.

If the protocol on your gauges is CAN and the GM is CAN, why can't you just send the signal to the current gauges from the GM ECU?
In your case, the speedo may be the only issue, as the sensor may be in the transmission output, not the rear end.

If you can wire a car stereo, you can install his kit. When we talked, he indicated he could modify the GM harness and ECU, and provide a wiring diagram to follow. Kind of like a Crutchfield install kit, with plugs. For you motor mounts, you will need the ones that look like this.

The dodge gauge system is not the can system. I checked a list of supported vehichles and Dakota did not do it until 05. It has a "pci" one wire system. I'm not sure what that is but Will look it up. My mounts are different than that so I'll get some 5.9 ones from a junkyard unless I can find new ones. It would be nice if Jared can retain all the body functions of the dodge and then wire all of the engine vitals and control into the Chevy computer. I don't really "need" to use the can bus from a newer Chevy but the idea of having all my engine data on an I pad is pretty appealing.

So here's what I've discovered. If I want to try to use the can bus system to do my gauges on an I pad I would have to get a gen 4 engine and harness. These have a 58x reluctor wheel and some other changes to the engine. They also use flat top pistons and have a 9.9 to 1 compression. I'd rather not do that high of compression because I intend to turbo it. My local salvage yard has a complete 01 5.3 (lm7) engine harness computer all accessories, and trans for $1350. I think I'll be better off getting this set up. I like the idea of an I pad gauge, and variable cam timing but it is out of my budget right now. Maybe in a future swap.

Here are the pinouts for C1, C2 and C3 from your current PCM. You can also get Torque Pro app for $5 that gives you almost everything (all gauges, including speedo). It works very well.
