It's a lot more than circuits and wire! How often have you seen advertisements for wiring harnesses promising, 21-circuit kit for the low, low price of...? What do you get for that low price? 21 circuits and yards of colored wire? Is that all you need, and exactly what makes up a proper wiring harness, anyhow? Well, it's a lot more than just circuits and wire. A wiring harness is, first and foremost, engineering. At Painless, all of our harnesses are designed by real engineers using the latest in diagnostic equipment and AutoCAD to ensure consistency in manufacturing and an accurate and easy installation. Finally, and certainly not least, there's quality. You deserve the assurance that after installing a harness it's going to work: That when you turn on the headlights, they shine; That the blinkers blink and that the engine starts. At right you see a Painless fuel injection harness on our exclusive test board. Every single fuel injection harness, before it goes in the box, is mounted first on a test board like this. Each blue connector simulates a particular engine function. This test ensures that all connections are working properly, all pinouts are correct and there is continuity in all the wires. When you install a Painless harness, we GUARANTEE it is going to work. If you're looking for superior quality, engineering and craftsmanship, Painless is your only sensible choice. Painless has remained the leader in automotive wiring and electrical products for over seventeen years through engineering and innovation, not corner cutting and imitation.

What if I am not available when the carrier tries to deliver?

If there is no response when the package arrives, the driver may leave the package nearest to the street or make a second delivery attempt on the next business day. Please check your tracking info as it will let you know the next steps for delivery attempt.

I have special delivery instructions (i.e. Leave by back door, leave with neighbor, place in the planter on the left of my garage, etc.)

We recommend leaving a note for the carrier on the door nearest to the street as we do not have a way to communicate those requests for you.

Why did my item ship from a different location?

Many parts are stocked in more than one warehouse location. As a result your order may ship from a location other than the location shown in the listing. In most cases the shipping location will be closer to delivery address as we always try to ship from the closest warehouse to minimize transit times. In some circumstances intraday sales and other inventory changes may result in your item being shipped from a location further from your delivery address.

If your order is over $250 there is a possibility it was shipped with a signature required option. The easiest way to check is to locate the tracking number for your order and open on the carrier’s website. There is no additional cost to you for this service.
