The Green wire... - Page 2

Brad01mc · 03-09-2007, 07:35 AM

Hi!

I had another project that I had to finish last night, so I didn't have a chance to bench test anything. I'm pretty confident that my CDI is fine. It still whines (I know, it's only part of the box).

Yes, I will clean all connectors.

Also, my electrical has been hacked by the PO...installing multiple alarm systems over the years. I've pulled out all that crap and will re-organize all of the wires over the week-end.

As far as those connectors, I plan to make a trip to the local pick-a-part and snip off a few of the connectors, once my green wire arrives. If there is a part number on anything, I'll make sure to share, or tell you the type of car I take it from. I've seen that style connector on my old BMW...or was it the Mercedes...anyway, it looks familiar.

Thanks again!

Brad,

Another view of pigtail installed:

Here is a better view of the nolg-nosed connector needed to mate with the pickup coil in the SC distributor ... ignore the 2.7 distributor:

Here is a Bosch Fuel Injection connector that could be installed on a one-piece cable like yours, after the darkened & frayed part is cut off -- to mate with a fabricated or factory pigtail ... less than 1/10 the Eagle day price:

The outer shell of above female connector could possibly be trimmed with a Dremel and carbide PC board router bit ... just going out on a limb, brainstorming, here ... to mate with the magnetic pickup coil connector:

Note the long 'snout' part that is required to go into the distributor body:

Revised drawing to show 6-pin CDI connector layout for testing ... looking into the harness connector:

I used the factory pigtail. That meant I had to get a Bosch "fuel injector" plug, and a (faston?) connector for the CDI box. If the "faston" connector has the little tab on it, then it neatly replaced the factory connector in the six-pin block, and it stays put.

Early_S_Man · 03-10-2007, 10:58 AM

I still can't tell for sure whether the connector that goes into the distributor is an Amp Junior Timer or Amp Junior Power Timer??? The width of the tabs on the pickup coil would seem to imply Amp Junior Power Timer, rated at 25 Amps.

This is the 'standard' female terminal Amp Junior Power Timer connector shell:

Hi!

Just an update...

Well, good news. I found a source for the connectors into the distributor, of all places, in the junk yard!!

For $2, I was able to pull a green dizzy wire!

The source...old V-8 Mercedes S class. From the '70's! Yup, they share the same connector! They have a funky round coax like connector at the CDI end, and a nice bosch connector at the other.

I was also able to pick up some AMP ends out of BMW 325's. I also took some other similar looking ones from VW's. I'll use the one that works the best.

So, I just cruise around the yard looking for these car types, and if I find something that does not look dry rotten or burned up, I take a look.

The Dizzy connector that I found is still white, not yellow, in color! The wire was covered in thick grime, so it seems that it was protected.

I also decided to buy a MSD 6AL. I got it for $230 (new), so I can't complain.

So, what I'll do is play with my new collection of parts and see what happens. When my new pig tail comes in, I'll use it and connect it up to the MSD.

Anyway, if you are looking for green wire spares, I suggest that you pack your 13-15mm socket with extension, a screwdriver and go parts hunting.

I have 3 wires now!! More than enough.

I would still like to find an original source for the bosch part, and in the mean time, I'll just keep cruising the yards.

Thanks again, and I'll keep you up to date on how it all turns out...

One quicky, can I use a stock coil with the MSD?

Thanks!

Brad

Brad,

I recommend the MSD High-Vibration coil #8222.

Here is a cheaper source for the 2-position Bosch/Amp connector and pins [have to be ordered separately] that needs to be added to any cable mating with the pigtail out of the distributor:

How did my bearing-tool go? The tool chest drawer misses its tenant. Plus, I dont want to spend your deposit.

According to the specs in German, the dimensions are the same but the rating is different.
Contact-material and contact-area are different for the 25A but the outside dimensions for the plug are the same as the 20A.

Anyone know which terminal is for the center wire and what terminal is for the wire that wraps around it?

As you can see by the photo, the notch on the one side of the connector is facing the camera

Brad01mc · 11-20-2007, 02:44 PM

Use an Ohm meter, or voltmeter (set to Ohms) to test continuity between the old connector, it's plug/wire and compare it to the new.

So, if the plug that goes into the dizzy has 2 slots side by side, put one probe in the right side of the connector and figure out if it's the center wire or the one the wraps around. Once you figure this out, you should be able to repeat the procedure on the new plug to determine which is the right way around.

Does this make sense?

If not, the worst case is that your timing will be way off and it will probably backfire and run like crap if you've got them reversed.

AngM018 · 11-20-2007, 02:52 PM

The issue is, my old wire didnt have the connector on it. It was wired strait to the 6 pin. I dont have an ohm meter but could pick one up. I am just not sure which wire is which without having to cut the new wire at the connector

Does anyone know what these parts are called? i went to the Kayjayco webpage to order them, however....the site has photos showing them but they are not labeled...and they have many different product selections but im afraid im going to order the wrong parts...thanks.

Go to a junkyard with your side-cutters..
These connectors are used on other cars; I found many on different VW models.

FULL END-TO-END GREEN WIRE SUPPLIER FOUND!!!

Reviving a very old thread here to share some info I have discovered about the infamous Green Wire. As we know, the one provided by our host and most their suppliers is too short and need to be spliced in to the original cable and removing/bypassing the older, cooked section.

I hunted everywhere for a solution and ended up reaching out to the guys at Kroon Wire who make pretty much every kind of wire/engine harness you can imagine for all our cars. The can provide the CDI harness as a full replacement which includes the original Bosch Distributer Wire:

https://www.kroonwireharnesses.com/index.php?route=product/product&product_id=711&search=6+pole

It is expensive but very well made and a great replaceent preserving the original wiring specs of our cars. However, after emailing them they are very aware of this issue and while it is not advertised on their site that explained the following"

"We could also deliver a green wire at the right length with terminals that you can "click" in to the 6 pole connector. Please note that the distributor connector is not available as a single part (unfortunately) so will need to mount a 2 pole Bosch connector at the other end of the cable and that will connect to the famous short Bosch green distributor wire. (male to female). The price for this will be EUR85,- ex shipping ( the original Bosch wire is included)"

So thought I should share this here because it looks like a great option for anyone who needs to replace their Green Wire (perhaps me in a few days... we shall see)

Spend the money on getting a spare CDI module.

the OE installation of the green wire is shielded. But in reality any wire of like 18 gauge will do. You just need to get the square wave signal to the CDI.

I disagree on the Bosch CDI I have done lots of experimenting and testing on my 2.7 MFI motor. My car runs MUCH better on a good aftermarket CDI and I have lots of other benefits like soft rev limiting instead of that stupid centrigugal rotor, and data gathering.

The Bosch CDI is a 50 year old electronic deisgn......think about that. Most of the components belong in a museum. If it has been in use for 40 years, gee that is not a risk I want to take when I take a drive.

My Bosch CDI is in a nice little box in a cabinet in my shop.

I am not a big MSD fan, but there are many good choices available.

I have had my car for 20 years and the best thing I ever did was to replace the Bosch CEI and take out the points. I could finally have a strong running reliable engine.

I chose a Daytona-Sensors CDI and swear buy it. Soft rev limiter, data gathering, programmable, and it has been dead reliable for 15 years.

Put you Bosch CDI on the shelf.

229 Euro for that harness??? ARE YOU KIDDING. You just need a wire of like 18 gauge. I could be green, or it could be any color. I guess if you want to keep the coucours judge happy, you can spend the money.

NOT ME!!

URO Ignition Distributor Wire 930 602 907 01 is for 1978-1989 911 and 1978-1979 930, and is approximately 128mm long. We've recently modified this wire slightly with updated connectors, which grab the pins more securely than our first production run.

Wire 928 602 907 00 is technically for the 1978-1984 928, but has the same connectors and is 725mm long. Which means it can be used in place of 930 602 907 01, if additional length is needed.

Edit: We aren't discontinuing 930 602 907 01 after all, and will continue to offer both lengths.

timmy2 · timmy2's Garage

Looped and zip tied?? Sounds appealing... and should look great! (NOT)

Why drop the only low priced alternative to the current $75 and up Bosch or Porsche supplied units?

A 3 foot wire with only the distributor end installed would be better for restoring an original style SC harness.
The turbo and some row cars all came with the replaceable short wire, and most that have fixed their bad wire have gone to the short wire. So those customers won’t go for the loopy look....
