Painless Performance Products - Since 1990

The wiring aspect of any LS swap is undoubtedly the most difficult. Most builders are familiar with fabrication techniques, trouble shooting, and parts swapping to make things work, but electronics rise to a much higher level of complexity.

Wiring has carried an aura of mystery that can send a shiver down the spine of even the most seasoned builder, making them wish for a simple carburetor and distributor. This chapter has the answers you seek with easy-to-understand instructions for tackling the wiring of an LS swap.

Retrofitting the stock harness requires knowledge of electrical circuits, soldering skills, and attention to detail. It is not a simple plug-and-play procedure, so make sure you are up to the task before hacking into the wiring harness. On many LS engines, even the throttle is computer controlled; the pedal is connected to a sensor box that tells the throttle how much to open.

These systems can be overwhelming, but the key is to tackle one circuit at a time. Although the factory systems are certainly adequate, the aftermarket has fully embraced the LS platform and there is definitely more than one way to do it right. If you picked up an engine from a salvage yard or other used vehicle, you need all the electrical components to go with it.

Let me repeat: it is imperative to get everything. This includes the computer, wiring harness, mass airflow sensor MAFoxygen sensors, and if the engine is drive-by-wire, the gas pedal and throttle actuator control TAC module.

Each engine requires the use of its own specific computer and harness, and keep in mind that there were changes made to each system year by year. In order to reuse as many of the factory components as possible, you need to get all of them with the engine. Keeping track of each wire can be a bit of a headache, though. Whether using a stock or an aftermarket harness, the cleaner the install, the better. This Painless Performance PowerBraid protects the wires from abrasions and heat while keeping a stock look.

Friction tape at the ends secures the braid. Regular electrical tape works, but make sure it is good-quality stuff such as 3M Super The cheap stuff falls off. Each Painless Performance kit comes with all the basics: terminal pack, relays, and zip ties. You often need more terminals than what is included, so be sure to have plenty of assorted terminals on hand. Bulk terminals can be ordered directly from Painless. Here is the completed wire-diet LS1 harness install with the full loom.

This takes some time to complete, but the results are worth it. Retrofitting a stock wiring harnessis seemingly complex and perhaps overwhelming. In fact, it is really not that difficult. With the proper diagrams and instructions, it can be modified to greatly simplify the process of wiring the engine. The majority of the wires in the stock harness are not needed in a retrofit application.Here is some helpful information if you want to modify your stock truck wiring harness your self This junction block is part of the main engine harness, that screws into the bottom of under-hood fuse block.

If you want to use the whole fuse block you can, but I like to keep it clean, and wire a lot of these together. There are a lot of wires here. Each injector has its own power wire all the way to this block.

All 8 of them can be wired together into a single fuse to clean things up. This is what is done inside the fuse block. Be sure to look at the pictures of the harness at bottom of this page.

That is all to get a much cleaner look, and to simplify things later on if you have to troubleshoot anything. Provide fuel pressure to the rails, turn engine over with starter, and it will run!

This would be the most basic simple way to run. There are signals for brake switch, tow haul, all of which are found in the connectors near the fuse block connector. I don't recommend just combining all the pink wires into one and powering it. You are asking for issues if there is ever a short, including melted wires, fire, so on. Click for info.

Re: 5. Quote from: V8 Supra Builder; I used 8 fuses for my LM 7 swap, computer constant power, computer ign power, computer ignition power 2, coils even, coils odd, front o2, fuel pump, and MAF.

I just cut that connector off and put a couple Weatherpack connectors on. OK, more info C1 connector GM designation light grey color contains the starter solenoid wire, position C10, purple with white trace. Connect this to the wire that went to your old starter solenoid. Also, A9, pink, is switched ignition return from the ignition switch. Connect this to the circuit that used to power the ignition coil.

Architectural wiring diagrams play a role the approximate locations and interconnections of receptacles, lighting, and surviving electrical facilities in a building.

Interconnecting wire routes may be shown approximately, where particular receptacles or fixtures must be upon a common circuit. Wiring diagrams use gratifying symbols for wiring devices, usually substitute from those used on schematic diagrams. The electrical symbols not abandoned enactment where something is to be installed, but also what type of device is beast installed. For example, a surface ceiling spacious is shown by one symbol, a recessed ceiling blithe has a alternating symbol, and a surface fluorescent lighthearted has complementary symbol.

Each type of switch has a swap metaphor and for that reason realize the various outlets. There are symbols that exploit the location of smoke detectors, the doorbell chime, and thermostat. A set of wiring diagrams may be required by the electrical inspection authority to approve association of the address to the public electrical supply system. Wiring diagrams will as a consequence tally up panel schedules for circuit breaker panelboards, and riser diagrams for special facilities such as fire alarm or closed circuit television or additional special services.
