Topic: Four way flasher location

[C5ZZ]

Just looked at the 65 wiring diagram and it shows the orange extension wire
with the blue wire going to the cigarette lighter, looks like I need to find one
of those or make something up.

Mine doesn't have the black metal bracket and there is not a need for it,
the hole in the dash has a flat side which lines up with the flat on the
switch so it fits in perfectly. Also the wiring on mine is a little different
from yours, I don't have the blue extension wire and it hasn't been cut
off, I have two of these flashers and they are both the same.
Maybe mine are from a factory install where yours is a over the counter accessory.

I have to check the wiring on my flasher sometime.

I have these switches under the dash and am guessing at least the fog light switch was dealer/owner installed since the car is not a GT.

Yours may or may not be missing the black metal bracket.

Here are some pictures of a NOS unit I dug out tonight:

I think that what you have is the service flasher, not the factory version. How about listing the part number on the harness tag?

If you could check where yours plugs in and let us know that would be great!
One wiring diagram I looked at showed the orange wire going to the fuse box,
the other diagram wiring diagram showed the extension and pluging into the
wire for the cigarette lighter.

Jim, the harness tag is long gone, when you compare them mine is just
like yours except that you have the bracket and the wire extension.

Look at "rodster"s picture, his is mounting to the dash just like mine
without the bracket.

Found emergency flashers listed as a option in the 65 sales brochure.

Good point, yes it is a service flasher. Service part # on harness is C5MB-10C840-A, Box is C5MY-15B584-A.

C5MY would be a Mercury part number, maybe it was used on the Comet also which was similar to the Falcon.

I use AGX-20 fuses in that spot.

[C5ZZ]

Fuse replacement on instructions specify a 20AMP B-14526 fuse. From what I reference that would be a 5 pack of B-14527.

Picture from Ebay:


As you can see on the side S.F.E. 20 AMP.

Bussman specs:
SFE-14 length: 1-1/6", 27mm
SFE-20 length: 1-1/4", 31.7mm

Problem is the SFE-20 will not fit the bottom horizontal 14A slot on a 1965 Mustang fuse box.

I've read discussion on this issue, but have not seen any answers on what Ford used for a 20 amp fuse in a 1965 fuse box.

Any information out there?

As Midlife mentioned AGX-20 would be the way to go.
Here is the chart for fuses from the Ford MPC.

Fuse instructions:

Thanks for the info.

Do the instructions still show for Mustangs application that
the orange extension wire with the blue jumper wire is used
or is the extension not used on a Mustang? If so where do
they show it plugging into?

[rodster]

The flasher itself looks longer than most I've seen, is it a unique piece?

Yes, emergency flashers are different from regular flashers,
four lights flashing versus two, if you look on it there is a
different number, 536 for four way flasher, 552 for turn signal flasher

Did you happen to get a chance to see where your harness plugs in for power?

[C5ZZ]

Fuse instructions:

Maybe you can check your flasher but noticed on mine
it had stamped on it to use a 14A fuse, maybe the fuse
doesn't need to be upgraded?

[midlife]

Extension wires (female plugs) are not used in Mustangs.  I believe they were put there for temporary lights (like a movable light to place on the top like a cop car?).

[midlife]

That's correct: one wire accepts the cigarette lighter female bullet and passes it on to the lighter itself.

My earlier post refers to the 66 harness that has two female extension leads on the driver's side that don't appear to be used for anything.
