6-conversion rewiring

[farleyd]

Hi to all, while converting to a six, you need to change tachometer. Which i did. Couple of questions about the wiring. I just cant read flow chart and wondering if 1974 has different wiring than 1973.

I have a 1974 with stock wiring, and a dash left gauge with temp on the top, and middle row of lights: brake warning, volt, (white) and oil (green), and fuel gauge below.

- - -

1973 charts say brown/white to brake warning light on the left dash gauge. I have brown/yellow to one pin. Whats the colour of the color on the other pin?

- - -

Does 1974 has separate turning light circuit? 1973 charts say two cable: one should black/green, the other should be black/white. Mine has only one, and its bk/gr/wh????? Does this mean that there is no separate left/right flasher light on the 914/4 1974 tachometer? The 911 i have do have. What to do?

- - -

What fuse location should i plug the fuel pump wire if i want power to my fuel pump to be available on both IGNITION and CRANKING.


Hope i am clear.

Sabin, could you post a copy of my e-mail reply to you on this subject? I don't have a copy available at the moment, and it might help out others on the BBS...

For the fuel pump, you can use the existing Fuel pump relay. Just run a wire from the relay board's T4 connector to ground. I think it is pin 3, but I need to confirm. Anyway, works well for me. I would add an inertia switch just in case...

A: There are a few differences...


Q: I have a 1974 with stock wiring, and a dash left gauge with temp on the top, and middle row of lights: brake warning, volt, (white) and oil (green), and fuel gauge below. 1973 charts say brown/white to brake warning light on the left dash gauge.

A: Black/Green/White. This is found on track #44, item K7. Two con-
nections, one br/yw, one bk/gr/wh.

Q: Does 1974 has separate turning light circuit? 1973 charts say two cable: one should black/green, the other should be black/white. Mine has only one, and its bk/gr/wh????? Does this mean that there is no separate left/right flasher light on the 914/4 1974 tachometer? The 911 i have do have. What to do?

A: The 74+ cars have one single turn signal light in the tach. Some early-production 74s had 73 tachs, with two arrows. Both were hooked to the same wires and flashed at the same time. You'll probably have to do the same thing with yours. I suggest running them in parallel, or just hooking up one bulb. The turn signal bulb is K5, on track 45. Its one connector gets a
black/white wire, and it is grounded through the body of the gauge. You may need to run a separate ground wire to each bulb, as well as running another
wire from the power connection of the one bulb to the power connection of the other.

Q: What fuse location should i plug the fuel pump wire if i want power to my fuel pump to be available on both IGNITION and CRANKING.

A: As I've said before, fuse #9.

Thanks Dave!

Another rewiring question about my 1974 914.

I desesparatly looking for the turn signal wire behing the main gauge. Looks like there is no one, and as i cant read 1974 flow chart, i am lost. I tried with a tester to find a wire that clings with the flasher to no help. What color is it?

The switch for the hand brake is borken. Would that be why the red warning brake light is constantly falshing?

Many thanks!

Hi Sabin,

Look at:
http://www.pelicanparts.com/914/parts/Electrical/914_electric_74C.jpg
K5 is the bulb and J1 is the switch.

the track is 45. This is located at the bottom of the page (black letters in the yellow section). Find 45, go up, you will see the turn signal indicator K5) with a blue/white wire comming from J1.

Does the flashers work and it's only the bulb in the instrument cluster that doesn't light? Does the emergency flasher work? Just trying to rule out the flasher relay.

As for the brake warning light,read:

This might cure your flashing brake light in the cluster.

Sabin, re-read my note.

... The turn signal bulb is K5, on track 45. Its one connector gets a black/white wire, and it is grounded through the body of the gauge.

As for your brake warning light, if the wire going to the handbrake switch is grounded, the light will flash. That includes if the switch has shorted to ground.

Hello while i have the tech specials here in this thread

I am rebuilding a 914 to a 914-6 where we yesterday try to implement a 911 Tachometer.

We had issues with the wiring. The year of the wiring is unclear 1973 or 1975.
From the turn signal we have Black Green & Black White to the hazard switch
and 3 wires on each side to the turn signals. Front/ Rear supply from the flasher.

We cannot find any wires to hook up the turn signal lights R&L into the tachometer.

Is this normal. Was there a 914 version which had a different indication of turn signals

Up through 1973, the 914 tach had separate right and left turn signal indicator lights. For the 1974 model year, that was changed to only one light indicating either turn signal was on. (N.B., some early 1974s used 1973 gauges with the silver center and two indicators in the tach, but they were both wired to blink together!)

That may be the cause of your confusion if your 914 is 1974 or later; there are only wires for the one indicator light.
