As you may know, I am 'sperimentin'. I have five 06B 905 115L late model 1.8t coil packs (which are POS, coil and plug connectors all in one), five 4B0 973 724 empty four wire connectors (to mate to the 115Ls), ten 000 979 133 A two female spade connector pig-tails, the S4 and 1.8t wiring diagrams, lots of reasonably colour-coded wire and crossed fingers.

I am trying to do this completely plug and play (no cuttting of any original wires). I have solved the problem of the coil power connectors (I will let you know the details later) BUT I haven't been able to solve the POS connector problem (yet). This is where I need somebody's help.

I have figured out the wiring from the ECU to the N122 and N127 POS units (Note: The Bentley is wrong about N127 for cylinders 4 and 5). What I need is a four flat pin connector to take the place of the POS connection so I can plug it into the four pin connectors from the ECU.

I hadn't really thought about it before but the electrical system is inherently quite safe. Input power is carried in female electrical connectors (in this case spade connectors) that, in turn, are carried in male plastic housings. The powered device,
e.g. the POS units, have male spade connectors in a female plastic housing. So the power connectors are physically shielded by plastic bits, which obviously makes shorting things out difficult (but not impossible).

What I need is a four pin connector with a female plastic housing with four male spade connectors to mimic the POS.

I scoured a VW wrecking yard on Saturday (the Audi wrecker was closed) and didn't find any suitable four pin connectors, perhaps, because IF there were any, they would be powered devices, not actual connectors.

My thoughts at this point include a) finding 2 dead POS units and hacking them to relieve them of their 4 pin connector housing (not pretty and not really very plug and play for others to follow (if the whole thing works)) or b) buy some male spade connectors, get the spacing correct by plugging them into the POS-trigger signal connectors from the ECU (ignition way off) and then "casting" them into epoxy (just to fix the spacing). The latter is more DYI but would require two tie wraps to hold the result into connectors from the ECU.

I am open to other suggestions. (I have talked to AMP by the way - "restricted parts")

Remember these all-in-one 1.8t coil packs cost $30 each. (If this works, everybody will benefit).

'dummy' plugs to replace the POS's, but for a different project. I'm putting a v8 4.2 motor into a CQ and will run 034 EFI on it. I want to use as much of the factory wiring harness as possible which means bypassing the POS's since my ECU has built in coil drivers and can fire the 3 wire coil directly. If I find something I'll let you know...

I didn't really look around much on the site, hopefully it helps.<ul><li><a href="http://www.eagleday.com/connectors.html">http://www.eagleday.com/connectors.html</a</li></ul>

No. Thanks. I will.

Dave, this is the place I was refering to in my email

spiralsmurf

are you keeping any of your info secret? or are you willing to share and help me out so we can both get this done.

The Librarian

This will not be a secret. I am only holding one thing back so far.

spiralsmurf

which is what? the coil power connectors?

The Librarian

That is correct. I will email you off line.

spiralsmurf

did you send me an email?
