2nd Gen Non-Engine/Transmission High Beam Wire...which one is it?

Hey Everyone... .



I am in the middle of wiring up a new set of driving lights. I want to tap the high beam wire so that the relay triggers the driving lights to come on when the highs are on. Which wire is it and where is the easiest access to it?



Thanks in Advance:)

Be aware that your model year 2000 Ram completes a ground (switched ground) to activate the high beams. Twelve volts is always present at the lamp filament. You will need to use a relay with your new lamps and wire the ground of the relay trigger coil to the high beam ground wire.



Several years ago I did exactly what you are trying to do on my model year 2000 Ram. I tapped the high beam ground wire at the passenger-side lamp. I don't remember the wire color. A meter should find the wire quickly.
 
my re wiring directions for the sport conversion say that the red/orange is LOW beam and that violet/white is HIGH
 
On 2002 diagrams Hi beam is RD/OR, Low beam is VT/WT, and 12V feed is VT on the left and VT/RD on the right. My 01 is wired this way also. If you have quad headlamps PK/RD is the feed for them and LG/BR is controlled to ground.



As mentioned they used ground side switching, so run 12V to the relay control coil and tap into the RD/OR ciruit by the headlamps to get ground when the hi beams are on.



Solder and shrink tube the splice, please don't even consider scotch locs (wire taps).

I agree with Wayne, Scotchlocks (wire taps) are the most half a$$ way of tapping a wire. Can cut the wire and corrode to the point of a bad connection.

Ps. Hope I didn't offend the millions of people who use these;)
 
TTT

I will install some driving lights as well and I am learning how to use relays. When the switch is used to ground the the circuit as the high beam is, how do you wire the relay? Simple instructions please as the gray matter in the brain is rather dense on occasions.

Thanks

SWC - With the "switched ground" you need to connect a fused source of 12 volts to one side of both the trigger (control) coil and the switch portion of your relay. The other side of the trigger (control) coil is connected to the wire that goes from the bulb, through the in-cab light switch to ground. The in-cab light switch is completing the circuit through the trigger (control) coil. I'm in agreement with Wayne's post above and would connect this second side of the trigger (control) coil to the RD/OR wire that comes from the bulb.

The other side of the internal switch in the relay is hooked to one side of your add-on lamps.
