Picture of a 981 CS ... 981 GT4 is the same 
 
The Frazerpart sourced item above has the M8 eyelets, if you purchase from CTEK they have the option of M6 & M8

Our 981 Spyder came with a "free" Porsche battery conditioner (Rebadged CTEK) - but in came with the 12v power plug to go into the internal socket.  I am looking for an adapter(?) or even multiple converters to have a permanent connection (via spade connectors) on the battery and feed to cable in under the front avoiding all rubber seals.  
 
I can find cables with the spade connectors and with a small connector to tuck under the front hood - but none that will take a 12v plug designed for the old cigarette lighter socket?  Am I looking for the impossible or am I going to start cable cutting and build my own??
 
Thanks for any clues
 
Andrew


You need the CTEK connector that has the larger eyelets so that you can fit one side of the connection to the chassis point - either the wiper base or there is another point on the passenger side suspension turret that will take a bolt and do the same.  Do not connect both sides directly to the battery or you bypass the little black box that controls the charging regime - all explained in the manual.  None of the 12v sockets stay live in my Spyder - seems that at some point Porsche changed the software as some 981s work and others don’t.




 
I assumed that the battery charger would go direct to battery and that it would control the charging process - must read the manual!
 
But I still have the problem that the connector has a 2 pin plug on the end and the Porsche version of the Ctek has a 12v power plug designed for the in car  socket?  Time for a bit of build your own adapter?

Can you post a picture of what you have ?
 
My understanding is that you have a male aux socket on the output of your charger  - that can be attached to the female ctek cig socket - that can be connected to the battery / chassis via the ctek / Fraserparts connector ?

This looks like my charger and the image appears to have the connectors needed - is it M8 size?  Where do you hide the female socket so as to get easy access?

The fused battery - chassis connector from Fraserparts has M8 terminals, picture shows where connector resides when not in use ... the bonnet has a recess in this area hence no interference 
 
To use ... it has sufficient length to reach the trim aperture at the w/wiper - from there connect to the cig socket section - then to charger ... if you require more length Fraserparts can supply a 2.5m extension lead

So I can source the connector from the battery to the connector within the recess - I just need to find a cable to connect to that battery and to the female cig lighter socket - this is the one I have been unable to find.

The items in post 24 will do what want ... going left to right in the picture 
 
1. Attach M8 ring terminals of fused connector lead to battery and n/s suspension turret, the other end of this is a female CTEK connector (incorporating a traffic light battery condition indicator) 
 
2. Use the male CTEK connector of the CONNECT Cig socket lead to attach to the female CTEK connector above 
 
3. Use the female socket of the CONNECT Cig socket to connect to your charger`s male adapter 
 
4. Plug charger to mains 
 
If you require additional length of cable then Fraserparts can provide a 2.5m CTEK connector male / female extension - this can go between the battery connector lead and the CONNECT Cig socket lead

I can source the M8 connectors to the ctek connector, it is the ctek to female 12v supply I seem unable to find on frazerpart website - the one you refer to as connect cig socket lead - where did you source yours?

Great 
 
I didn`t see the CONNECT Cig Socket with Frazerparts but on the CTEK site and Amazon, I don`t use one myself

Before you buy the adaptor try putting the Ctek into the socket in the passenger footwell, it has been mentioned before not sure if on here or PistonHeads but if you put the Ctek into the socket before you switch off the ignition then it does not cut out after the allotted time, I have tried this on my 718GT4 and it stays live.
Also if you speak to any OPC they will advise to fit to the positive battery terminal and an earth on the body. This is standard practice across most manufacturers, in fact on Mercedes and BMW they have specific earthing points.
