I would move them down to the bottom far corners of the grill.

Still not the best look but if I was trying to make the best out of what is there?

It's been long enough... Where da pics at?
No progress yet because of my bad rear axle seal. Now that that is done I might try to figure something out this weekend for them as far as mounting goes and maybe run the wires, but I don't have my switches in yet.

Hopefully I'll get them in this weekend :fingersx:.

I'm hoping to work on my LED lights and my HIDs (which are supposed to be here on Sat) this weekend.

I need a little help on the wiring though.

I found a great thread on GMT400.com about the High-4 mod.

I do need some help with the LED lights though.
Here is what I'd like to accomplish with them:
I want to use a relay so that when the parking lights get turned on/off, the LED lights will go with them (I will also be able to over-ride them and keep them off with a switch in the cab). This way I will never leave them on when I turn my headlights/parking lights off. To do this I think I need to use the parking lights as the "signal" to the relay. The actual power to run the LEDs will come from the AUX post on my fuse box. I am concerned that by doing this, the LEDs will flash with the blinker.
Can anyone tell me if they will flash or not with the blinker?
If they will, where should I get my "signal" from?

Being as specific as possible would be greatly appreciated.
If anyone doesn't follow what I'm saying, I can try to explain it better (maybe).

As little current as the LEDs use, I'd think you could just wire your switch in series with the power for the parklamps. How much do the LEDs pull amperage wise?

No, they won't flash with your turn signals if you hook 'em into the park lamp circuit. Two different circuits involved there. Just hook the power to energize the relay to the parking lamp circuit and then use the N.O. relay contacts to switch power from the AUX post to the LEDS. Put a switch in that line between the LEDS and the relay and you'll have an "off override" that will keep them off no matter what.

He probably could, but it's better to use a relay anyway, just in case he ever puts a real load on the park lamp circuit, such as hooking up a trailer with a lot of lights, etc.

Oh, and I forgot to mention he should put a fuse between the relay and the AUX connection, just in case. 2.5 amp would be plenty, but they can be hard to find, so maybe a 5 amp (more common).

I agree a relay would be best.

Where might I find the park lamp circuit? - I take it it involves more than just hooking onto one of the bulb's wires then.
What are the N.O. contacts on the relay? - I'm gonna have to get my relay and look at it so I get this all straight.
Which wire goes to the off override switch: power or ground?

Oh, and I forgot to mention he should put a fuse between the relay and the AUX connection, just in case. 2.5 amp would be plenty, but they can be hard to find, so maybe a 5 amp (more common).
I already have a fuse to put in line, but I'm glad you said where to put it.


I realize I'm asking a lot of questions, but that's why I'm here and I don't want to screw this up and burn my truck down.


EDIT:

here is what my relay says (the cardboard backing)
30 - terminal for lights
85 - terminal for relay ground wire
86 - terminal for switch -- I'm assuming this is the wire from the park light circuit?
87 - terminal for power source

So if I'm reading this correct, I need to run a wire from 30 to the LEDs, 85 to a ground, 86 from the park light circuit (where ever that may be), and 87 to an inline fuse then to the AUX post on my fuse box.
Where does the swich in the cab fit into this mix?

Yup, you got it right. Put the switch in the cab between terminal 86 and the park lights. That way, with that switch "off" the relay does not get power. Finding the park light circuit is easy, just turn on the park lamps and see which wire going to the parking lamp has power. That's your park lamp circuit. You want to put the fuse between 87 and the power source. And N.O. stands for Normally Open, meaning the terminals on the relay that are normally unconnected when the relay is not powered.

So, to recap, wired the way I've described, in order for the LEDs to be lit you will have to have the parking lights on and the switch in the cab. Without the parking lights being on the switch in the cab won't do anything.
