Electrically retarded...need wiring help
Ok, as shown in this post....
https://www.ranger-forums.com/forum2...ad.php?t=29892
I'm attempting to wire up a 2nd toggle switch to power my KC lights.
I have the following image from Rwenzing:
I have nothing plugged into the 86 or 87A ends. I had wired up a female connector to the LB/BK wire to connect to the 85 end, and then wired everything as shown on the image above. The result, no KC lights, the ramger OEM fog toggle still powers my fog lights and the LED illuminates. If I turn that switch off and toggle on the new switch it also illuminates my fog lights, but the LED does not illuminate.
Wire colors are as follows and in order:
OEM wire harness
1. tan/orange
2. blue/red
3. black
4. blue/black
New 2nd switch harness
1. tan/orange
2. red/black
3. black
4. blue/black
I removed the female connector I mentioned above (tied into red/black) and tried splicing red/black to blue/red. Same results, fogs, but no KCs.
Bob (rwenzing) told me to do the following:
Currently the tan/orange wire on 2nd harness is sliced into the green KC wire (load wire). The only thing I can think of is to undo the slice and then splice it (tan/orange) into the white KC wire (supply).
Any suggestions? Help! LOL

Here's what I would do:
White to 30. This MUST have adequate gauge wire for the load and be correctly fused near the source. 12 gauge wire would probably do it unless the wire run is very long.
Green from 87 to the KC's. Again, adequate wire gauge for the expected current.
The 5A inline fuse also connects to 87 and supplies power for the "ON" LED in the factory switch through the switches tan/orange wire.
Brown. This won't be used because it is the ground for the LED in the KC switch.
The factory switch grounds through the black wire from the harness connector and this can be teed into the black on the real foglamp switch. Same story for the blue/red night illumination wire - it can be teed to the blue/red at the real foglamp switch.

The RD/BK is also dash illumination on some Fords so tying it to the LB/RD is fine. The BK grounds can also be spliced.
Make sure that you do NOT have the TN/OR wires or the LB/BK wires of the 2 fog switches wired together. All 4 of these must be independent.
After fixing the above (if necessary), then you will need a switched 12v trigger on pin 86 or the KCs will never work. This could be from the ignition switch, the high beams, the low beams, the parking lights, etc. It all depends on which modes you want to allow the KCs to operate. The 2nd fog switch would still override that trigger to turn the KCs off when desired.

Edit:
LB/BK are sliced together (oops). Still need a switched 12v to connect to pin 86 though.

Whenever the ignition is on, regardless of whether the other lights are on or off?
Only when the high beams are on?
Whenever the high beam, low beam or parking lights are on?
As I said before, any of the 3 options above would be overridden when the new foglamp switch is in the 'off' position.

I went ahead and looked up all three for 2004. To make the relay functional, a wire needs to be connected to pin 86 and the other end tapped to one of the choices below:
Hot with ignition switch in RUN: gray/yellow at HVAC selector panel.
Hot with high beams only: light green/black wire at pin 25, brown connector, SJB
Hot with headlights/park lights: solid brown wire at pin 8, brown connector, SJB
Keep in mind that none of these have been tested but they look good on paper.
There should be enough reserve capacity in any of these circuits for the additional current load of the added relay. However, if fuse melting becomes an issue, it is possible that the tap may have to be moved somewhere else.

Your last statements worry me. the 87 pin/tn/or wire is spliced into the green KC wire which is fused by KC (I forget how much, but I believe it's more than 5A). The white KC wire is also fused, so I'd like to think I'm fine there. If I do blow a fuse by tying into the SJB what would you recommend? Apparently all this seems to be a first. I'm smelling a potential sticky or some sort of mild write-up. What a PITA this has turned into! I think I need to make friends with a local electrician.
I'll have results after 8pm MST. I get off work then. Right now I have about 25 minutes left for my hour break.

- The large wire in the above schematic that comes to pin 30 should be sourced from a constant hot (like the battery or equivalent) and fused close to the source for safety. In this case, I believe that you are using part of the KC harness that already has a fuse, probably 20~30A.
- The added 5A fuse is just for the small TN/OR wire that branches off to the 'ON' indicator LED. It needs to be there because a tiny wire like that should not be protected only by the 20~30A fuse.
- The existing truck fuse for the LB/RD for dash illumination.
- The existing truck fuse in the SJB that protects the wire that you will tap to power relay pin 86.
In all likelihood, there will be no fuse problem from the addition of that relay to one of the existing circuits. I only mention it because it is remotely possible.
Yes, the HVAC panel is the control panel for the heat/AC located below the radio.

If I have to have the radio bezel off again it'll be too soon. Of course that'll either be sunday or monday when I wire in the OHC.

I'm doing the exact same install. I only want the KC lights to come on when the car is running and at least the parking/running lights are on?
IT looks like I need to find the wire to hookup the keyed 12v (what color do I need on a 2001 Ford Ranger for them to be on with the lights on) and the dash lights power wire? The rest of it looks easy. I just need the proper connection for those two Ford wires and I should be good to go.
Thanks,
Zach

For KC operation with the head lamps/parking lamps, I would wire the hot side of the relay coil (pin 86) to the brown wire at the headlight switch.
For the dimmable switch illumination, tap the light blue/red at the radio or HVAC control panel. (The color code in the foglamp switch pigtail may be LB/RD or RD/BK depending on the donor vehicle.)

I will attempt this in the next coming week or two and will be sure to post pictures.
I'm hooking the KCs up on the light bar soon but still working on my dash surrounding the radio.
Thanks again.
