1967 Cougar Turn Signal Indicator Bypass

- Provided your Sequential System is working, this will bypass the 3 Relays used for Indicator lighting. Replaces 'dimming' with 'on/off' signaling. Taps the existing Front Signal Lamp voltages and routes them to the Indicators.
Bullet connectors (male/female) available at Auto Parts stores. - Auta a dopravní prostředky
Thanks, it has a way to go to make it right, but I rescued it from the field it was in, and will nurse it back. I love the straight lines of the first gen.
And your wiring chart looks awesome ! I took the factory diagram had it blown up to poster size and colored it in, but lost it to moisture, yours is still way better! I'd owe you BIG for a 68' diagram!
Thanks, the chart is redesigned as a functional chart for troubleshooting. I was going to do the '68 next, but I am assembling my Coug right now. Maybe over the winter, it'll be posted on the forum when I do.
Unfortunately, after looking, I do not think this will be feasible on a '68.
This method is sort of how the 1969 indicators are wired, '68 was a hybrid.
The turn signal indicators look to be ground switched rather than load switched, and one connection goes through the steering harness plug, not an easy jumper to make.
Plus, you only have 1 relay which would be eliminated, the turn signal indicator relay, which acts like the K7 relay in a '67, producing the flasher pulse. The '68 has only 1 Emergency Warning relay, the trunk unit. The forward one (K6) is eliminated as Emergency mode (both flash) and L/R switching comes from the Steering column cam, which also means the 67's K5 relay is not needed. This method eliminates the K5,K6, and K7 on the 1967, which was the direction Ford took in later years.
Here is a partial of the 1968 diagram showing the factory indicator wiring. The only relay you need for them to function in a '68 is the flasher (K7), and WCCC has plenty. You can see though the indicators are reverse wired through the flasher, which is a ground switch action, them rather than giving them voltage.

Partial, whole, I don't care the more info the better Cheers !! And as far as relays that's not a big deal being a heavy equipment mechanic I had to figure out how to wire and rewire relays early !! LoL
Sweet, skills are good! Always a pleasure to help someone who can run with the ball. Here is a down and dirty of what the '68 bypass would have to look like:

It reverse wires the bulbs, making the ground side HOT. The bulb socket ground should and MUST be isolated on the 1968, or you'll send the voltage straight to ground when the turn signal is on.
I cannot verify this, but it's NOT on the '67, so you must be sure!
AirWingAce Isolated should be a 2 wire plug on the bulb BTW. Ground is on the wire not attached to frame.
Greg you have me pretty jealous. Ive always wanted a first gen cougar
It's funny because I just joined after "lurking" (very cougar'ish) for YEARS the sites really "grown up" I'm on as Renegdzcoug.
It has been pointed out that this would eliminate the CLICK noise for the turn signal as well. My half disassembled car carried the trunk relay noise, so I missed that little bit *facepalm*

So.. To ask the question, (and I am interested) what is the use of this "mod" if the system is working? I have a 68' that needs to have its system repaired after moisture, rust and butchery. More info and maybe a diagram laying out the wiring change would be great. Thanks Sam.
When I say working SEQ system, I meant that the SEQ motor and Relay (trunk) are working. The remaining 3 relays (attached to wiper motor bracket) are eliminated. That is the benefit, not replacing those 3.
You also lose the click sound from the flasher relay, and '67 is different from '68 there, so the mod removes getting it wrong and shorting out everything. (putting a '68 flasher in a '67 will do that)

I will work up a chart showing the re-route
Maybe I'm missing something here, but why re-wire when you can just use new relays in the old circuit. I realize the concours correct relays are expensive, but you can buy 30 amp generic relays at your local parts store for $10. Or I think WCCC has new style relays with modified connectors that just plug in place of the old ones.
+Jeff Schlarb WCC has restored OEM relays, and some modern replacements, but not necessarily for the indicator relay.
The Indicator 'flash' system is different for just about every year. 1967 is load switched, 1968 is ground switched, but both depend on current load to close an electromagnetic coil, which is generated from a motor cam changing contacts for 3 bulbs.
In 1969 they basically do what I have done here,.
There is no need for time circuits, but glad your putting EC101 to good use. I was building those on a Radio shack kit board when I was 12.
