For pretty much any application, single high/low, individual high and low, 1 bulb, 2 bulbs, 4 bulbs. This is the "old" style that involves cutting and taping into wire harness.

Installation is pretty simple:
Cut low beam wire, use wire taps to connect the cut wire ends to two wires on the modulator.
Cut high beam wire, use wire taps to connect the cut wire ends to two wires on the modulator.
Mount the photocell.
Tap into horn wire (optional).
Connect ground wire from modulator to any ground point.


I used this for several years on my C10, never a problem and definitely improves visibility.

I bought the C10 in 2002, probably put this in in 2003 or 2004. Still working strong til the day I pulled it in 2011.

If you still have this, I'll take it.

Curious, what's the purpose of optional horn lead tap?

Still have it, PayPal is fine. The horn tap is an optional connection. You attach tot he horn lead and when you hit your horn it will force the modulator to flash 3-4 times whether it is on or not, even at night. Just a little visual attention getter to go along with the horn.
