The project 710K Begins.

[Alaskantinbender]

I finally took the time to start playing with my 710k Pinzgauer. I’ve had it for Over 10 years now, got it as a basket case in Alaska. Moved it to Arizona 5 years ago and it’s been siting out back waiting for its turn under the wrench.

Todays update.
The pinz adventure continues. Fuel tank and electric fuel pump mounted/plumbed. next up is wiring up a 24/12V power supply and fuse block to power the 12V pump and any 12V accessories.

I couldn't resist taking the time to mount my hood ornament using the factory holes.

What's your plan? Restore to original condition? Ultimate off-roader? Rugged cross-country touring machine?

Is it driveable at all? If it is, I'd contemplate removing the body before you get too deep into it to address any drivetrain/suspension issues.

[Alaskantinbender]

I plan to use it as a SW desert exploring/touring machine. It does drive and doesn't make any expensive noise. The brakes and lockers need rebuilding. Lots to do, just putting it all together so far. We will see what happens as I continue with the project. I have been pretty heavy into old Land Rovers for quite some time, so this is a change in direction for me. This is my 63 109 I used to explore Alaska with.

Solid-looking starting platform overall — it reads as honest rather than “improved to death,” which is a good thing.

On the electrical side, I’m sure you’re already thinking in this direction, but I’ll share it anyway: I’ve found it best to keep accessories 24V wherever possible, and only feed a 12V converter to the handful of items where there truly isn’t a 24V option. It keeps the system simpler, reduces converter load, and generally behaves better long-term.

On the farm jack — I mounted mine in the same location for the first few years until I received similar advice: That’s a lot of weight to have coming back at you in a forward impact. Worth thinking through before you commit to it long-term.

Glad to have you in the Pinzgauer community. Looking forward to seeing your progress on the project.

[Alaskantinbender]

Thank you, Great advice.
I have learned a tremendous amount over the last week or so on the forum.
It's a terrific wealth of info.

[Alaskantinbender]

Still lots to do while waiting for brake parts to arrive.
Today, I installed and wired the headlights and got started trying to sort out the taillights.

[Alaskantinbender]

Still sorting out the tail light wiring. The color schematic I have is for a 710M, not a K. Most of the colors are different. But I have my trusty volt meter.
And I don't seem to have a junction box as depicted in several photos online.
There is a constant "on" black wire in the right rear wire harness. It must be for a power plug.
And look what came in the mail today. A quicky volt meter and my co-pilot.

I hate to be the bearer of bad news, but you’ve planted Vault Boy exactly where your future GPS speedo antenna puck is going to live. Really hoping he’s on a mag mount… otherwise he’ll have to get evicted.

There is very little difference between the color schematic and a K.

However, I do have a K schematic (Funkkommandowager) I can email you
if your interested.

Ha Ha, good call. And yes, he is magnetic.

I have a black-and-white 710K schematic from the forum. But thank you for the offer.

Yes, this is exactly where your Garmin Overlander goes. My mount is secured with both zip-ties and adhesive. Belt & suspenders is essential in the Pinz.

On the left side, here's my solution for DC power jacks -- I added a double-wide standards-size (still 24VDC) receptacle in front of the euro style socket.

On top is the voltmeterhttps://a.co/d/0hcQomdq.
This is probably the best 24V tolerant charger I've found: https://a.co/d/04SOAyS0

Here are some of my wiring notes that might help you. Also I've attached a .PDF of the color wiring schematic I've used on my K.
Also, I modified the original taillights to be US standard and support dual-filament bulbs.
I found these https://a.co/d/0ai9mbex to make excellent back-up lights. No holes need be drilled, and you just replace the factory reflectors. Wire in a reverse switch to the transmission with a resistor for reverse lights, and a bypass switch for full power for trail use.


Errors in schematic:
- Front right side headlight running light from CB2 is GRY wire, not GRN.


Modifications for my 710K:
------------ For US STANDARD TAILLIGHTS ------------
- ORG wire inserted into rear cable connector (was tucked in jacket) under
dash
- ORG wire removed from four-way flash circuit control
- ORG wire is now brake lights
- Taillights modified to use dual-filament bulbs in lower section
- Rear taillight blackout light bulbs are now #1829 (70mA) vs. SAV suggested
184mA version
- Rear taillight/brake light bulbs are now SAV3502 -- same as #1662 (29W/?W)

------------ For BACKUP LIGHTS ------------
- Both left and right taillights now use BLK wire. Before one was
BLK and one was GRY
- GRY wire into rear junction box is wired to LED Backup Lights
- GRY wire from rear cable assy removed from CB2
- GRY wire at rear was removed from trailer connector since function changed
- For dim backup lights, GRY wire under dash is connected to CB12 through
200-ohms which is sent to the transmission switch over the red wire. A 50V
1N4001-type diode is in series to prevent back-powering.
- For bright backup lights, GRY wire under dash is connected to CB11 directly.
This circuit is powered always except in blackout modes. A 50V 1N4001-type
diode is in series to prevent back-powering.

------------ For TACHOMETER ------------
- Added GRN wire splice into GRN wire from distributor to ignition coil
- Added BLK wire splice into speedometer light for tach light
- Changed tach bulb to 28V version
- Connected tach power to CB10 (maybe) -- same circuit as fuel gauge

------------ For SPEEDOMETER ------------
- Original backlight bulb is OSRAM K45617, 24V/2W (measures 110mA at 28V) --
bulb tested as intermittent on the bench
- This is sold as SAV3504 #09-40-11
- Replaced with SAV3510 which is 184mA @ 28V

------------ For FUEL GAUGE ------------
- Original backlight bulb is OSRAM K45617, 24V/2W (measures 110mA at 28V)
- This is sold as SAV3504 #09-40-11


------------ For REAR JUNCTION BOX ------------
- 1: PINK Blackout (on in S3 light switch position)
- 2: Unused
- 3: Unused
- 4: BLACK Taillights
- 5: BLK/WHT Turn signal, left
- 6: BLK/GRN Turn signal, right
- 7: ORANGE Brake (new)
- 8: GRAY Backup lights (new) -- repurposed


Interesting notes:
- There is a 24V accessory plug on the driver side of center hump near front
wall of body. Untested.
- Trailer connector untested
