Looking for a little help....
I completed the install with little difficulty. After finishing I connected the negative cable and briefly smelled an electrical burn?????

Everything in the truck works and I checked almost all of the fuses with nothing to report.

But the lights don't work.

I have power at the newly added 20amp fuse, 1 power lead at the relay, and the switch icon illuminates and dims with the dash board, but the green indicator doesn't illuminate.

Can anyone help?
Does anyone have a wiring diagram which shows the that wires should be hot? (constant/switched)

Any help is appreciated

Are you sure that you got the wire into the right hole in the connector in Step 20 of the instructions? That is the most common mistake.

Another thing to check is the last part of the install under the dash.
This is an excerpt from one of my posts on the 3rd page of the link above.

*****************************
I performed the fog lights operation, along with the accessory grill Labor Day morning. It took about 3.5 hours. the grill was cake, the pdf for the fogs could have been clearer in spots (more technical explanation, not this wire here...dat wire dare...). Ex. During the last part of the install where you wire the harness under the dash, why didn't they say to plug the blue 5-pin connector which was assigned to the cruise control button to the blue connector on the harness...?! The install went great, looks great and works like factory.

Thanks guys.... I think I made those connections properly, but I'll check tomorrow.

If that's not it...
Any other ideas

or wiring diagrams

The Service Manual doesn't show the pieces of the fog light harness that are fitted as standard. Maybe someone who has the Electrical Manual can check that.

Thanks, anyone have the electrical scematic?

The only diagram I have is the circuit diagram that came with the install instructions. Sounds like the relay may be bad since it powers both the indicator light and the fog lights. Are you able to check if you have power at the 4 pin connector that connects to the relay? If so, it sounds like the relay is the problem.

Sorry to add, I did the install yesterday with success. Thanks to all that posted their trials and tribulations on previous threads.

I just reread your post, you indicate that there is power at one of the leads of the relay connectior. With the leadlights on (and the brights off), you should have power at two leads (this would be the red/green wire).

Just a BUMP

Sorry I don't have any answers for you. From the way you describe the problem, you are missing the low current feed that energizes the relay. Power to the 20A fuse is the high current that will feed the lamps via the relay, and I'm assuming that it is the same power that you're reading at the relay (ie do you lose that if you pull the fuse?). The switch night-time illumination is coming directly from the jump off the Cruise Control switch, so is expected to be working regardless of anything you do under the hood. Did you say that you only have power to one pin on the relay? That would indicate the switch is on the positive side and not ground.

Did you check the connector and red/green wire that I mentioned? I'm fairly sure that is the 5A feed either from or to the switch. If you did get it in the wrong connector pin hopefully you haven't fried something else, although a burning smell isn't encouraging. The schematics will really come in handly figuring out what you may have indavertantly supplied power to.

Lingered I has come thru again. You had the answer from the start!
In my haste to see my fog lights energize, and in frustration with the "lock" on the 18 pin harness, I made the connection to the 3rd from the right.... not the 3rd from the left.
After correcting my mistake, I HAVE SEEN THE LIGHT.
Everthing seems to be Ok, but I'm concerned about what damage I may have done?

Now, does anyone have any idea what I accidently tapped into?
Or did I hit nothing at all...

Time will tell.

Thanks again for all the help.

Glad you got it working. That connector has bitten several us. Hopefully you didn't fry anything.
