For many 1967-1972 Chevrolet C10 trucks, the factory-installed tail light harness is not adequate for today’s needs. If you are looking to upgrade your C10’s tail light harness, there are a few things you need to know. The first thing to consider is what kind of bulbs you will be using.

If you are using standard incandescent bulbs, then you can use a standard wiring harness. However, if you are using LED bulbs, then you will need an LED-specific wiring harness. There are a few different brands that make these kinds of wiring harnesses, so do some research to find one that will work well with your particular setup.

Once you have the right wiring harness, the next step is to install it. This is a fairly straightforward process, but it is always best to consult with an expert if you have any questions or concerns. In most cases, all you will need to do is connect the positive and negative wires from the taillight assembly to the corresponding wires on the new harness.

Once everything is connected properly, test the lights before reinstalling the taillight assembly into your truck bed. If done correctly, upgrading your C10’s tail light harness can be a simple and effective way to ensure that your taillights are functioning properly. It is also a good idea to upgrade if you are planning on doing any other electrical upgrades in your truck, as this will give you peace of mind knowing that everything is compatible and up to code.

The 1970 C10 tail light wiring harness is a pain to work with. The wires are brittle and break easily. The connectors are hard to find.

And the instructions are confusing. But, with a little patience and some elbow grease, you can get it done. Here’s how:

First, disconnect the battery. Then, remove the old harness by unscrewing the two bolts that hold it in place. Be careful not to drop anything into the engine bay!

Next, grab your new harness and start threading it through the firewall. It helps to have someone hold the other end while you do this. Once it’s through, connect the two halves of the harness together.

Now, it’s time to start connecting all of the wires. Consult your instruction manual for which wire goes where – it’s important to get this right! Once everything is connected, tuck all of the wires away so they don’t get damaged or caught on anything.

Finally, screw the new harness into place and reconnect the battery.
