Tapping high beams.

[OFC Ranger]

Is it more common practice to tap it somewhere in the harness, or just tap the line right before the bulb socket?

I would assume the harness but I am curious as to what you are trying to accomplish

Going to tap a triggering line to my spot light relays.

They are all in the wire loom behind the left headlight , right beside the battery on my Lariat . I tapped the park lights there.

With that said Stedi does have a plug in harness that should work. Be aware you also have to have another harness with it to work. Another member tried and went straight to the lights but I don't believe it worked.

I don't see why it would not work. All a trigger line for a relay is, is juice to complete the circuit with the relay. Technically I could make it so my spot lights come on everytime I press the brake pedal. lol

I am curious what the problem was, because from a basic electrical standpoint there should be nothing to prevent it.

I'll be running a one way diode in my harness so I can still use the spots on a regular switch without triggering the high beams and so they don't back feed each other.

I can't say how the other guy had it wired up. Using it for like a relay or something else you would think it would be fine. If anything Stedi uses a little module for the signal circuit

Those quick tap type connectors in the picture above, they are considered to be a poor way to tap into a circuit, I would suggest a proper crimp connection with sealing heat shrink.

The amount of times electrical problems are traced back to one of those would surprise you, at least it's under the hood, somewhat protected, but it is the headlight circuit, don't want a problem with that one.

Just look at the pic, nice sealed connectors, to prevent problems, last a long time, and then there is the tap......

Just my 2 cents, feel free to disagree.

Yea I stay away from those splice taps. It takes almost no time to make a proper 2 to 1 connection with self soldering heat shrink butt splices.

I love these things:

If it is a harness that requires multiple inputs I invest in a junction box like this:
