i was sent a distributor plug for a 1.9 engine in order to make a tester. decided the best route is to keep the 2.1 plug and add the 1.9 to the same harness to eliminate any connection issues. while i was doing this, i replaced the duckbill open barrel connectors as the one's in the 1.9 plug were corroded.
i'm still trying to source the 1.9 plugs. i have something very close but would require shaving the plastic guide ridges off. if you have a spare 1.9 plug i'll modify a tester for you to do both the 1.9 and 2.1 distributors.

Two last resort ideas to repair wires/connectors to dizzy hall:
- harvest wires/terminals from a Mk2 (or even Mk3?) VW harness. Or possibly a Mk1.
- wires, connectors from generic relay socket. But, the terminals are likely too big.
I find a bent and shaped paper clip or as-is small jewellers screwdriver works ok to release those terminals.

No worries! It’s a great find - Just wanted it to be clear for others who run across this in the future.
Dan - how much for a rig with no plastic connector or bail connection (I.e. individual terminated wire ends as described above)? I’d like to see if I can rig up an option for the 1.9l crowd. Maybe eventually sourcing a 3-d printed connector block would wrk if I can find a donor for someone to model.
Cheers,
Jason

This is the pigtail connector. In case anyone needs a link to the one that works.

Just to be clear, that connector won’t work with the 1.9L hall sender on the dist. See pics in my post a few posts previous. |
Sorry sorry
Forgot to mention this is for a 2.1L.

correct, the wiring is the same, just the molded plug is different. i have a 1.9 Hall sensor and just haven't matched up anything.
those crimps, same as all over the Vanagon, are called "open barrel". usually you pick up a crimper with replaceable dies, i'm using the 20-18 gauge slot of 3 slots. i'm using a Pro's Kit CP-336F but i'm not particularly enamored with it. others are probably better.

Thanks Dan - it seems the wiring on the pigtail end is the same, so I imagine it's just the harness that is different. Maybe some generic rectangular 3 or 4-pin housing (the OEM one has an offset detent, but maybe a generic one with a detent could be ground down?, or even a "open-ended" connector end (maybe with thin heat shrink around as much of each connector as possible to shield them) with the 3 individual Digikey connector-terminated ends which could be connected to the sender unit? I'd be happy to be a guinea pig for such a device!
Cheers!
ps - here's a few pics of the connector and sender unit connection.
Pss. can I ask what sort of crimper / crimp block is needed to properly terminate those digikey connectors? Want to pick up something fairly inexpensive, but that will do a decent job on those and other electrical connections (terminations and in-line heat shrink connections.

i have not been able to source the plug for the 1.9 and it definitely is different than the 2.1, won't fit. i would absolutely tool some up for the 1.9 if i could find the blasted plug.
to me there's two advantages to the tester... one, you can quickly test your sensor in less than a minute if you suspect the distributor so it is great for the road kit. secondly, since it is self-powered, you can sort thru any spare distributors and KNOW that they have a working Hall unit, all off the car.

Small problem with that line of thought, the above ^^ units are only for the 2.1 wbx and are stated not to fit a 1.9 wbx. Durn, once again we 1.9'ers are left out in the cold...   |
this development is bothering me as i assumed the 1.9 and 2.1 used the same Hall plug and receptacle. i've looked at photos online and it appears the 1.9 dist end is more rounded. standby!! more research being done. |
I'll let you know when my Tester arrives- At worst, it means changing out the connector for the Distributor if it doesn't fit exactly. |

Dave Barton confirmed that he has those distributor plugs for $6 so i'm dropping the price to a more reasonable $75.
thanks to bridgetroll13 for saving y'all $10!!

that's a great question! i carry this as a troubleshooting tool so that i can definitively and really quickly rule out the distributor as a 'no start' problem. to me, that is much preferable to pulling the distributor at the side of the road, installing a new $80 one, and either carrying a timing light or guessing on the timing to try to start the engine. THAT is the utility... snap it on, test distributor, look elsewhere if good. i hate the crapshoot shotgun parts replacement method of diagnosing.
i've given the parts list and schematic to build your own at far lower cost, which narrows the equation because you don't pay for $9.45 shipping and an hour of my time. i offer this for those that just don't want to build one. for me, that's expensive but for some, it isn't expensive or is worth saving the futzing around building one. but i'll always defend the utility of quickly knowing whether your sensor is good or not!

okay, this is promising and thank you for the lead!! i've contacted Dave, the site owner, to see if he has stock. if so, i'll immediately drop my price $10 (and refund jlrftype7!!). standby!

i send these out with a fresh Ray O Vac battery... 5 year shelf life. with the tester unplugged, there is no complete circuit to the battery, meaning zero quiescent current draw.
being self-powered, they are handy for sorting thru distributors in your stash... no add'l power needed!
but i get your point. however, just lick the battery if you think it is dead. get a tingle, it's good.
