Anyway, the sealed and non-sealed connectors from a specific series plug into each other. The electrical tape found at local hardware store contains a lot of adhesive and may not hold up well to engine bay heat. What follows are the tools, tricks, and general information regarding the three most popular systems: Packard 56, the waterproof Weather Pack, and its more sophisticated brother Metri Pack see the Packard theme here? I'm trying to remove some now unnecessary pins from the wiring harness going to my ecu. Proceed with caution before reusing an old wire harness for your high-dollar retrofit. Just note that we wanted to include it as a less expensive alternative to fancy injectors. In fact, pulling the engine and all related electronic components from a complete donor vehicle ensures that you have system-matching parts that will play well together. Later years should be similar, use circuit 's to compair.

Different wire colors were often used. It was such a bargain that we bought two! This fit on my 94 Buick LeSabre like a dream. Be sure to look at the pictures of the harness at bottom of this page. Shown here are a two cavity and broad six-cavity connector. This is useful if you want to use a cruise control box. Don't worry about the little rectangular hole below the main hole. The one I was shipped did not include the additional red wire.

Custom Wiring Harness Build

Be prepared to spend anywhere from 8-12 hours on the build. Essentially the option is 4 more wires in the connector which statistically are not plug and play. A connector may be used for several different applications. Sent from my iPhone using Tapatalk To be clear, the upfitter package hasn't worked without a ton of additional wiring so I don't reply send those wires now. Some engine bays are left untouched except for oil changes and adding washer fluid; other engine bays have additional wiring for car stereo, alarm, nitrous solenoids, fuel pump relay upgrade, electric water pump, and the list goes on.

The recipe for a quality engine harness is rather simple: Use the same components and production tooling as General Motors did. Just knowing how to disassemble and assemble these connectors makes it far easier to strip engine harnesses for new installations. You must wire your fans through a relay. And they can be a real bear to connect and pull apart, especially when cold or in tight confines. This connector is a good way of bringing battery power into the cab without putting holes in the firewall.

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. Essentially it gives battery output that turns off after 20 min or before the load draws battery down. The Weather Pack release tool is little more than a thin-wall tube in a screwdriver handle. I have gone with Scoshe for a couple installs for features but the Metra dash kits seem better made, as do the harnesses. Chat with others, create a build thread, post questions and answers. Of the trucks I tested, none had the wires to utilize it.

Because the motor we are putting this on will require some massive injectors, it was cheaper in the long run, even with purchasing the injector box. Now the good: outstanding quality. This connector accepts two types of terminals. Please let me know how to order the 5 wire version from you. If it works, leave it alone.

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. Example: I want to use power from the x7 connector to a switch, then from the switch to the front of the truck to power a light bar. This story is meant to give you an idea what tools and techniques are involved as we show you some work from our 2002 Chevy Tahoe harness for a 5. I tried the usual parts stores and they pretty much said it was a dealer item but the closest dealer here is over an hour away. Provide fuel pressure to the rails, turn engine over with starter, and it will run! Additional relays required for fuel pumps, fans, etc. Do your research before you buy.

That is all to get a much cleaner look, and to simplify things later on if you have to troubleshoot anything. Without those, these connector systems can be a real burden. Most applications call for 150 and 280, but the information applies to 480 and 630. The non-sealed ones crimp like a Packard 56; the sealed ones crimp by the Weather Pack method. You may think that wiring is too challenging and difficult to tackle yourself, but if you follow along with us, you'll see that if you go slowly, and break each sensor down to its each individual components and wires, it's not as bad as it may seem.

The seal system also prohibits more than one wire from meeting a terminal. One will power the whole engine harness. They are colored coated wires, very similar to my car but my blue wire had to hook to a more of a deep blue, and the orange with white stripe hooked to a plain orange one. You are asking for issues if there is ever a short, including melted wires, fire, so on. Wire quality is important and they deliver. So I finally got back out into the garage and I'm having a bit of a problem. I either shortened or lengthened almost every wire in the harness for this modification.
