I tried the filed down nail approach when troubleshooting my idle problems but it didn't work for me :/
I'm interested to know what other people have done. Either way, at $28 it may be worth my while to get the real deal. _________________ '87 Vanagon GL Westfalia

Those are just the pig tails in that link. You still need the tool... _________________ '79 triple white convertible bug

We're talking about measuring current draw
of the ISV?
I used a "complex system of cables and pulleys" (jumper wires, various wire terminals) to shunt in my VOM. Saw no discernable readings with VOM set to DC mA. A much more knowledgable person suggested setting VOM to AC current draw. This seemed to work. (display current draw)
Was I on the wrong track?

I'm pretty stoked for this. Keep this thread alive, as I would like to do this also. |

I inquired about this harness with my local Snappy Guy.
A week later he gave me one.
Looking forward to seeing it in action.
I honestly dont even know what it is for... |

Last night UPS brought me a present!
One VAG 1315A/2.....
The measurement leads measure just the outside two terminals.
Rainy / Cold Wet day........ Haven't yet played with it.

I would assume the measurement leads are to and from one of the outside leads only.. One conductor is the ground, the other is a hot. You put your multi meter (on miliamp DC setting) in series with the hot conductor and measure the amp draw while in operation. It looks like the leads are threaded to fit common meter tips? Pretty slick |

Ever get to try that bad boy out? I went to go buy one today but it looks like they are sold out of 1315A/2 and only have 1315A/1. Actually, the link you posted now links to the A/1 version. _________________ '87 Vanagon GL Westfalia

I got tired of working with alligator clips and jumper wires and rolled my own today to help with the setup of a rebuilt 2.1
Harvested the connector and pigtail off of a parts Van.
The Yellow wire is the Positive lead.

sure! i'll qualify this is on my '87 with the 2.1... there is NOTHING about that harness that can't be replicated with a wire cutter and 2 terminals. notice first the plug... it has TWO leads with the middle blank. simple 12 volts that is pulsed to achieve a certain dwell on-time which opens the air valve an amount
so to measure the current, just cut one of the wires, doesn't matter which, and put the leads of your mA meter in between the wires and measure the current. it's pulsing DC or 'square wave AC' so your meter might prefer to be in AC mA mode.
mind you, i've removed the valve and hoses for a simpler life. works fine for me, YMMV as they say on the internets. _________________ -dan

I believe the idea of the tool was to nut cut the factory harness and introduce a future point of failure. But yes your observation is accurate. _________________ ☮️ |

a weather resistant M-F spade connection in a circuit that actually carries some current (vs a sensor circuit) is hardly a significant future point of failure given the overall foibles of our vans!
but, right, it is not the correct factory way and if this was a new vehicle and came back to me after dealer service with a bodge like this i'd be ticked off. i've got lots of bodges i rather like on my van now <grin> _________________ -dan

The tool specified is US 1119 ..... a common multi-meter, I've got about six of them, the probes go into the pigtails. Measuring milliamps.
"Tool US1119 Multi-meter (digital) "
Tool VW 1367 is unobtainium..... You can substitute with a tach and a timing light.

I found the VAG1367 tool on eBay in Germany a couple of years ago. Never really have gotten it figured out aside from picking up RPMs. The inductive pick up cable was still available new at the time as well.

I just wanted to add one more variation on the VAG 1315 A/2 for all those who don't have access to a parts van for that sweet plug: you can just use spade connectors to make up a testing harness. I had a box set of different size spade connectors. Female spades are good for multimeter probes to slide into, the smallest size male spades into the plug and the medium size fit the contacts inside the idle control valve plug. Obviously, it will fit or it doesn't:
Also, while we're here, if you're even bothering to look up this tool, there's a good chance you're going to need the next thing in the Digifant manual, the elusive US 1115 LED tester (VW later switched to a VAG 1527B, but those are hard to find too). I don't know why you can't just use a continuity test on your multimeter, but VW knows about those (the legendary "US 1119"), but still specs a US 1115. So here's how to make your own with a 1/4 watt, 330 ohm resistor, and LED, wire, and alligator clips:
This is what mine looked like:

For those of you wanting to create your own or looking for other plugs and sockets I ran across this guy...
https://www.prancingmoose.com/blackvinyl.html#EFIplugs
...who also makes an adjustable voltage regulator that fits our alternators as well. He has the connector for the 2.1 dizzy too.
