In the left of both pictures is the opposite gender connector that mates the new relay harness to the existing headlight wiring. The bulbs were expensive, didn't seem to last very long, burned out a reverse switch in my daily driver and if that wasn't enough, they were not very much brighter. If you find yours are wired backwards, it is a simple matter to swap the pins in the connectors. I put it all back together, flipped the switch and there was light! One screw holds the cover in place. This normally pulls on the high beams momentarily and may turn on the low beams as well. So you hook up the switch and the light in it is now shorting out the rheostat and that will mess up the dash lights. If you find a loose wire, you can try re-crimping it or better yet, use a soldering iron and solder the wire to the connector.

When running, a typical 55 watt headlight bulb has about 3 ohms of resistance. And since all the parts are interchangeable, you are not stuck with the bulb that came with the housing. I had to use a 10-inch ratchet extension to provide sufficient clearance. So it is possible to make the high beam indicator work as noted below. Also, the diagram is drawn for clarity and does not reflect the physical layout. Then the actual headlight bulbs are not hard-wired to ground, they are in a sense floating with respect to ground.

The harness is designed to accommodate horizontal headlight separations of approx. So, if you have a vehicle with switched ground wiring, just be aware of these sorts of issues when adding aftermarket devices that are typically built for switched power operation to any switched ground circuits on your vehicle.

Metal deposits on the switch contacts can result in a slight electrical connection even with the switch contacts open. The simplest way is with a large power resistor in series with the light bulbs to limit the voltage and current flowing through them. Now, the high beams are sufficient.

Total Chaos Caddy 2 kit, with kings up front and Deaver spring under in the rear. Likewise, on the female H4 output connectors, do the same with the Blue and Yellow wires. All 6 screws must be removed. You can test this case out with a volt meter or test light on your headlight connector to see which pins have voltage with high and low beams on. This resistor may be in the power or ground side of the headlights, it's location will vary with vehicle make and model. It did come with some awesome goodies though. The is just not a good enough reflector to put out a lot of light, so making the reflector better is probably a good idea.

I had the same problem on my 5-speed Sonoma and this was the fix. Then, using the two contacts in series, I'll run a 3rd relay to power the new reverse lights. First if your whole vehicle is wired with the swapped high and low beams, then swap both the input and output connectors on the harness. Easy way to tell is to look at the factory wiring diagram for the circuit you are interested in and see where the control for that circuit is in relation to the device is. Likewise, if the dimming resistor is in the ground side of the headlights, you'll want to conenect the wiring harness ground wires the black wires off the two new headlight connectors to the dimming resistor instead of directly to ground, as described in the first Toyota case above. Relieved of the added load of the primary headlights, the stock wiring should work fine with the lesser load. It seems the light from the bulb is more or less scattered all over the place instead of being focused to the back like you would expect.

The wiring harness also provides internal diode protection for the stock headlight switch as well as proper loading such that the high beam indicator functions properly. They are socketed for easy replacement for exactly this reason. For example, high beams work pretty good off-road for high speed night driving, except they leave a dark area just in front of the truck, so I've wired the fog lights such that I can turn them on independent of the headlights to fill under the high beams but not any more, see below. Likewise the high beam terminal should do the same switching between low and high beam mode. They have moving electrical contacts and those arc when making and breaking the high headlight current. However, the switch itself actually switches the grounds to the headlights and has to pass the full current of two filaments through it.

So in no way will the harness lead to a light burning out from too much voltage. This wire both sends power from the original headlight circuit to the low beam relay as well and sends power back to the high beam indicator on the dash. And why did Toyota and many of the other Asian automobile manufacturer's choose to use switched ground wiring in their vehicles? Typically less than 5% of vehicles seem to need the heavy duty resistor. For example if the power connection were to touch the case of the device, nothing would happen since it is not grounded.

Extra cab v6 4wd 5 speed. So for example if the daytime running lights are the high beams in a dimmed mode, locate the high beam relay that is the one with the two blue wires coming off it's 87 contacts and connect the heavy red wire with the fusible link and ring teminal attached to that dimming resistor. That is' use a relay with more current capacity than the lights need while running. For the cost nearly 0 and time under an hour total it is a good improvement and only makes you wonder why the separator was not mirrored at the factory? Likely would be of most use in off-road situations, anyway. The dielectric grease helps seal the metal-metal contact in the connectors and prevents oxidation and corrosion. That is if your charging system puts out say 13.

When the filament is cold, it has a low resistance. After drying, put the separator and lens back on the reflector and reinstall the assembly back in place. The brightest areas are about the same, but the surrounding areas or much more illuminated. I'm happy with what I ended up with, I realize there are other ways to do this, to each his own. Disconnect the wiring harness connector and remove the 10mm bolt.
