I’m close to having all of the connections made in the car. I realize everyone will direct me to vwar.org but maybe someone here can answer this.

When I removed the old wiring harness I did not take anything off of the trans, autostick controller, or gear shifter. Does this mean that the car should shift fine as it did before the harness swap?

The autostick control is fused in the engine bay but some diagrams indicate a fuse in the panel for autostick. I replaced my fuse panel and the new harness has no wiring indicated for the autostick system.

Thanks

Also, how is everyone organizing/mounting their relays? I have 3 relays that don’t seem to have any mounting hardware or location to be mounted. I’m considering cable tying them all together and then to the chassis support post in front of the fuse panel.


I'm zip tying them to the support posts for now. I should have either got relays with mounting tabs on them but these were already in my stock. I will probably make brackets for these relays to attach to the support post.

Well as I see it,as long as you have power to the fuse above the coil in the engine compartment,you should be able to shift..the Bentley states that if this fuse were to pop,you wont be able to shift..
The wire from the main fuse panel itself should go to the ATF warning light on the dash..you may have to get a piggyback female/male connector and put it on the according fuse to run the wire

Turn signal flasher relay issue:

49: two wires; one to fuse panel and one to 49 on emergency flasher switch?
49a: two wires; one to turn signal switch black wire and one to 49a on emergency flasher switch?

The harness kit came with pre-connected harnesses that fit this application. They look like a Y. Just checking it is correct before powering the car up.

Very frustrating.

Key out: emergency flasher switch sounds horn.
Turn signals not working
Emergency flashers not working
Brake warning light steady on
Oil and gen lights not working

I spent the morning going over the connections between a wiring diagram and the wiring works harness instructions and have no clue what’s wrong.

And the motor just generally runs like crap; seprarte issue.
I hate this car.

Definitely take a moment to chill breathe and relax. Then take another look at things. Think of it like a jigsaw puzzle with paint by numbers thrown in. Every wire has a color code , every switch/relay terminal has a number so you just need to sort them out . The linear straitness of the wiring diagram doesn’t match the abstract jumble behind the dash so you have to adjust in your mind.
Maybe snap some picks of the fuse block to see if others can give you a visual check.
Sounds like the problem is with the two top circuits(chart). What about head Lights and other circuits? Do you have a volt meter to check circuits?

Laughing We have all been where you are it. It has bern a long time and youve spent a fair amount of money too.

Take Deep breath, take a srep back and get a clear head.

These old Type I's are actually easy! No computers, no feed back systems, very few wires. (Though you're not thinkng that right now!)

As suggested, a few photos would help us help you. I'm only 45 minutes away, maybe after the snow stops.......... Rolling Eyes (have you seen Monday Nights "Possible Snowfall" Map?)

Post Photos, PM me if you are totally stuck.......

I have an all original 69 Ghia Autostick Coupe sitting here..........

Your problems are with fuse #1 & 2
These fuses are turned on by the ignition key. With the key off they should be dead.
Why are they energized?
What is feeding them +12v ?
Do you have a simple auto circuit test light?

The 4 way switch is feeding 12v to the horns.

Fuse #9 (unswitched, always +12v) is back feeding into fuse #1 & 2

I know you say you've checked everything but you are Mis-wired, probably at that confusing turn signal relay.

49 on the flasher relay has a wire going to 49 on the emerg switch and a wire going to fuse 1 (ignition hot). The emerg switch is powering the relay so that may be what’s supplying 12v to fuse 1.

49 relay to 49 switch and 49a relay to 49a switch are connected but 49 also goes to fuse 1 and 49a also goes to green and black on turn signal switch.

Very genrally speaking whenever you have electrical circuits that are misbehaving and operating in a way that shouldn't even be possible, then it's time to take a very close look at all of your circuit connections to Ground and be sure they are clean and solid.

... at least that's been my own personal experience, anyway.

In trying to figure out your wiring problems I stumbled upon the wiring in my 69 Ghia isn't like the diagram in the Bentley for 67-69!

My wiring diagram more closely resembles the 1970 Wiring.

I posted lots of photos in my Gallery, I hope they help you.

As mentioned, grounds.... grounds are EXTREMELY important in an old VW.
Many really odd unexplainable things happen with poor grounds.

THIS IS MY WIRING DIAGRAM! \/

This diagram looks like relay 49 (+) goes straight to switch 49 without going also to the fuse block.

Relay 49a goes to switch 49a as well as the black/green from the turn signal switch.

My relay 49 goes to switch 49 and also the ignition hot fuse. I think this is where my issue lies.

The JBUGS tips for the relay call for 49 to the fuse block, and the tips for the switch call for 49 to the relay 49. The relay gets power from the switch, so it shouldn't need to also go to the fuse block...

Key off, emergency switch sounds horn. Key on, horn works fine, but flashers / turn signals don't work.[/u]

Can you post some photos of what you are working with?

I am guessing that younhave the 4 way switch on the far left with multiple wires feeding it?

The flasher relay is mounted on the vertical member behind the speedometer?

You are talking about the White wire, yes it does

Relay 49a goes to switch 49a as well as the black/green from the turn signal switch.

4 way switch 49a (blue) goes to flasher relay 49a (blue) but it also joins the wire to the Turn signal switch.

My relay 49 goes to switch 49 and also the ignition hot fuse. I think this is where my issue lies.

Ignore Jbugs, they think you have a 67/68 when you actually have a 70 set up.

The JBUGS tips for the relay call for 49 to the fuse block, and the tips for the switch call for 49 to the relay 49. The relay gets power from the switch, so it shouldn't need to also go to the fuse block...

Key off, emergency switch sounds horn. Key on, horn works fine, but flashers / turn signals don't work.[/u]


Ignore Jbugs, follow the 1970 wiring diagram if your switches and relays are like mine.

I have double-triple-quadruple checked my connections.
Replaced my flasher relay.
Replaced all fuses.

Ignition off, the 4 way switch burns fuse 9.
Ignition on, the 4 way switch burns fuse 1 and 9.

Ignition on, the turn signal switch (right or left) burns fuse 1.

I'm fairly sure that the 4 way switch has now burned a brand new flasher relay.

Still working on figuring this out, and spending $$$ to get it right....

4 way switch:
30 to fuse 9
15 to fuse 1 (ignition hot)
49 to relay 49
49a to relay 49a
Side connection to ground

Relay:
K1 to indicator light in speedo
31 to ground
49 to 4 way switch 49
49a to 4 way switch 49a and turn signal switch

Fuse 9 is hot with key on and off.
Fuse 1 is hot with key on only.


Is this symptomatic of a bad 4 way switch? I feel like I have checked/replaced everything else.

If you have doubts about the switch, use a multimeter in its ohms or continuity range and buzz out the switch contacts for correct function in all states.

This thread has the four way switch operation described............
Wonder what prompted me to figure this out? Hmmmmmm......... Think
