Please help: Electrical connector for angled ignition coil

[Oz1200]

(2005 R1200GS)

I couldn’t get the angled coil/plug cap off the left hand side spark plug, so stupidly gave it a quite a tug. It came off with a rush and I managed to break the coil where the electrical connector goes in and crack the connector on the wiring harness itself. I can now see why the Haynes manual says disconnect the coils before removing them.

I can replace the coil – all it takes is money – and will attempt to repair the old one to keep as a spare.

The small 3 pin connector from the wiring harness that goes into the coil is a different issue. The plug is cracked right across and I’m worried it will fatigue over time. Whilst still serviceable (I think), I want to fix it. The local dealer was not able provide a replacement plug.

Can anyone help with a part number, or the name of the manufacturer of the electrical plug that goes into the ignition coils?

Does anyone know how to remove or install such connectors? They do look like they are supposed to come apart.

Any help would be very much appreciated...

Ignition / coils - cracks are bad!

Thanks IronandSteel.

I'm buying a new coil (number 3 in the above diagram). What I need is the 3 pin connector that plugs into that coil...

could be wrong but they look the same as on some jap bikes?

Mmmm....loom?

Breakers yard to take from an existing harness?

Dealer will know.

They do a "repair" part which is the connector + flying leads that you can splice into the existing loom. Can't remember the part number but a good search on here and advrider will turn it up.

try this

Thanks everyone, I'm cheering up a bit because:

1. Those links are very helpful, and now I have a picture of the part that I can show to various people.

2. I don't feel so stupid, because it appears I'm not the only one to have done this. Please be careful when removing coils...

I studied the part a bit closer on the bike. The boot type thing that goes over the plug has BMW 7 511 984 stamped on it, and the plug itself has 7 507 524 (no 'BMW'). The second number looks like the first, so I'm hoping it is a BMW part number for the plug. I'll ask at the dealer tomorrow, and follow up on the repair kit.

I've had a happy ending of sorts....The mechanic at the BMW dealer was able to salvage a plug from a BMW 135 car (apprently some sort of camshaft sensor) and splice it on.

I asked them to look for the subtle issue that made me start fiddling with the bike in the first place. They determined that the fuel pressure regulator was faulty (fuel was at full pressure, no regulation happening) and that a coil was faulty (so at least I was on the right track).


So it was an expensive visit to the dealer, but the bike is running sweetly now.

Lessons learned:

The repair plug part number referred to in links above appears to be correct, but none are available in Australia or Europe it seems.

The plugs are used in cars.

Be bloody careful when removing coils. They do seem to be easier to remove when hot. Someone in a different thread mentioned a dab of silicon grease. I might experiment.

I won't fiddle with the bike 2 weeks out from a 3 month trip again. This whole exercise has been a little stressful. I suppose the next step would have been a new wiring loom - imagine what that would have cost.
