Green Distributor Wire

Superman · 03-19-2002, 01:30 AM

My green distributor wire, the one that fries and gives people trouble, is looking kind of tired. the worst part is right at the bend as it goes into the rubber plug end. The rubber plug end doesn't look particularly replaceable. Anyone know if new plug ends are available for this little green wire? Something tells me they're not.

there are two types of green wire. one is a 6" piece that snaps into a connector from the main loom, and the other is part of the main loom. the snap on piece is the only resort, as the main loom replacement is impractical. basically, you have to cut the green coaxial wire, and attach the proper connector to it, so the short piece can be snapped on. don't mix up the outer braided wire and the inner thin wire.

Thanks, John. My plug is part of the wire loom. Will the 'other' plug fit my distributor, assuming I cut and splice properly? And is it available new or do I need to find an 'experienced' one?

both have the same plug at the distributor. the short green wire is part # 930 602 907 01. the plug end you need to splice into the main loom is the same one used on the air reg and warmup reg, etc. i have plenty of used ones.

in situ.

Okay, I have this 'pigtail' part and I even have some coaxial cable. When I re-wire this thing, does it matter whether I mix up the two conductors? I have already remove the plug and re-wired it so the car would run. When I did this, I lost track of which conductor went to which terminal on the distributor, but if it matters then I must have gotten it right since the car runs okay. Does it really matter...should I kep track of these conductors, or can does it just make no difference?

i never tried mixing them up. the wiring diagram shows a green on one side and a braided ground on the other. to terminal 7 and terminal 31d, respectively, on the CD unit. so if the unit is not grounded inside the distributor, which it is not, i would assume that you could mix up the wires with no ill effect. the electric speedo sensor is the same way. it just puts out a signal, regardless which way it's wired. try it and see. then we'll know for sure.

I guess I could find out right away, since my plug has been removed and the two wires to the alternator are independent.

Anyone know where I can find a plug to connect the coaxial green cable to the rest of the cable that connects to the CDS?

To echo Nitrometano, does anone know where the female connectors can be bought? John Walker says it's the same receptical used for the air regulator or warmup regulator.

.....squeak.

OK, I found the answer. They are located at:

If you reverse the wires, the engine will run retarded & the advance curve will
be wrong.

I don't think so. I doubt whether it makes a difference of you reverse the wires.

Those square plugs are all over the place. Any VW parts shop will certainly have them.

Kurt B · 12-13-2004, 08:50 AM

Hey will those connectors work on my fuel injection wiring? They look like the Bosch connectors. If so, that would be something I should do.

update: I read the page, and they say Bosch has used em. Wow, that might be a good investment at this point as my FI connectors are beat to *****.

Superman · 12-13-2004, 01:41 PM

That is what they are usually called, frankly. "Bosch Fuel Injector Connectors." Any VW shop. Any salvage yard too, frankly.

"don't think so. I doubt whether it makes a difference of you reverse the wires." - Superman -

Wrong! Avoid guessing at answers to issues.

1. The connector polarity is there for a reason.
2. The CDI is triggered by a sharp negative going edge of the distributor pulse.
If the wires are reversed the negative edge is slower and the CDI is triggered
at a later time (retarded).

Bottomline:

1. put a scope on pins 7 & 31 of the CDI.
2. reverse the wires and see what happens

Good point, Lorenfb.

A electronic fuel injector works. I get one from a electromechanic shop.

Please excuse a question from an electronics impaired Pelican, but why does the CDI/Dist connection have to include the coax?
Couldn't one run two wires from the CDI to the distributor (assuming the distributor plug & connectors were available as separate items).
This would seem to eliminate the troublesome and expensive coax.
What am I missing?
Thanks
