Making Your Flasher Relay LED Compatible Options

[Spoke]

This thread is meant to help those implementing LED turnsignals on their 914.

Standard flasher relays were designed to flash 2 standard bulbs (21W each) for turnsignals or 4 standard bulbs with 4-ways on.

LED replacements burn between 2W and 5W and electrically may not behave at all like a standard bulb. The LED replacements can cause all kinds of weird things like hyperflash (2x normal flash rate), dash indicators do not work, or the the flasher relay does nothing at all.

The 914 flasher is different for early cars 70-73 than later 74+ mainly because of the tach indicators. Early cars have individual L and R indicators and the 74+ have a single L+R indicator. Both are handled differently by the flasher.

There are LED-compatible flashers generally available at your FLAPS which are plug-in but not totally function compatible with the 914 standard flasher. The functional issue revolves around the 4th terminal which the 914 uses to activate the dash indicators.

The aftermarket flasher relays are EP26 (4 terminal) and EP36 (3 terminal). I've seen these at Pep Boys, Autozone, and Advance Auto to name a few FLAPS, usually for less than $15.

I'll detail the differences between early and late cars, as well as EP26 and EP36 in the next few posts.

This link to show Spoke’s easy mod works. I just did it on my 76 with the single indicator in the tach.
A couple of helpful hints if you’re planning on doing this.
1) use 22ga wire as its more flexible. Only needs about 1-11/2 inch piece.
2) the relay I used cam from my local flaps and the solder on the terminals was lead free.
I used a desoldering pump to remove the manufacturer solder and redid mine with rosin core lead/tin solder. Why you ask? The lead free melts at a much higher temp and doesn’t flow that well. Old style Pb/Sn rosin core flows much easier (less aggravating)

That’s all I got.
Enjoy!
