Most factory manifolds will fit any application. To be fair, this project will require a decent amount of free time. In general, pink wires at sensors are 12V power lines and black wires are ground. We laid our harness back on our donor engine and transmission to finalize the routing before we finished taping the branches in place. The process was repeated for each sensor on the motor. One other advantage to a new harness, especially on the truck engines, is that we route them differently and it just looks a lot cleaner on the engine. We had to purchase an injector driver box to help us run our low impedance injectors.
Adapter brackets are available from Street and Performance and Detroit Speed for mounting the hydraulic master cylinder to the firewall behind the brake booster. I don't see the logic there. Wires and more Wires Now that we have an idea what engine and hardware we have we have to figure out how to wire everything up. We wanted something that was waterproof for underhood use and provided extra room for additional fuses and relays. A Run an external pump to feed the feed line and a return line that goes to the tank. Signal conditioning is generally not required. I have put together a bunch of information on various wiring harness as I come across them.
Just use flared unions to connect them. If you are using an older transmission you can use a factory speedometer. The vast majority of people are more qualified to perform surgery, than to take on a task like modifying a wiring harness. However, the signal needed is opposite how you're brake lights work. Once you figure it out, there is a good chance it will be very difficult and or expensive to fix. Not only does it know the volume of air but it also knows the weight of air in pounds or grams. When you have everything figured out, buy the matching computer from a professional like Current Performance who knows the correct part number for your combo.
However, this is typically only an issue if you run your tank below ¼ full. So for that, we knew we had the right guy for the job. I've done disc brake and 5 lug conversion. If your transmission is modern, then you will need a gear housing that will accept a mechanical speedometer. You can find some helpful videos on YouTube to help get you through the process. I am running high pressure rubber lines from the intank pump to the regulator.
With the best Warranty, tech support, and quality be assured your wiring will offer to be one of the best investments for your project. Here's the 2001 Vortec 6. The decision for what computer really comes down to what the end product will be. You will find helpful tutorials and wiring diagrams on lt1swap. Our stock harnesses are 4 feet from the rear of engine passenger side. Working with your wire harness manufacturer to understand the systems will cover most issues with integrating those engines into an older chassis.
There are a lot of options available. Quote: Originally Posted by SatisTraction did any of you leave the diagnostic plug connected so that you could connect a tuner for the computer? Engine mounts, exhaust, gauge sensor hook ups, plumbing adapters, and water hoses are just a brief sampling of the hardware and parts that will be needed to complete everything. Unneeded wires are simply followed back through the harness and deleted. After cranking, power was restored to the coil through a resistor, lowering voltage to 6 volts. On top of that, knowing for sure what circuits to keep and what to remove leaves the harness in a state of experimentation. This leaves you with many fueling choices. After many long hours, we have stealthily run each wire to each connector.
If you are looking for a specific recommendation, we prefer the Hummer H3 oil pan, as in our experience it works well on all truck applications. For a lot of you guys out there, like us, you're probably cash strapped and budget conscious. If the engine runs too hot, it will automatically reduce spark. The computer is smart enough to see that the engine is running a little lean and will richen it up and learn that value for the next time you drive the vehicle. Pink power supply wires cut from this fuse block will be routed to the new standalone fuse block. Two weeks later a piston fell apart and the 8100 sent a rod out the oil pan and is now out of the truck, some pictures of the destruction. So I had them cut it in half put a flare collar on each side and put a double flare on the cut ends.
Some pins will be removed and a few may be added, depending on your application. This engine used different fuel injectors and pump to flow more fuel. Now, we have to cut or remove all of the wire terminals so we can only make the correct connections when we go back to rewire the system. You will find options and recommendations for motors and motor mounts, transmissions and flex plates, accessory drives, wiring and computer systems, oil pans, steam tubes, gauges, fuel systems, exhaust systems and carb conversions. Wiring Specialties offers a number of options for common performance upgrades for this product. The list of possibilities can be endless and extends as far as what that engine had to do in its original chassis.
