Base Model rear speaker wire!?

[calvinhorse 870]

I’m just trying to put rear speakers into a base model 205, the red plug for the head unit clearly has the 8 wires for the 4 speakers...

 

the fronts I can pretty much chase all the way to the speakers but the rears seem to go upwards and disappear behind the dash? 
 

surely they end at a plug somewhere? I’ve checked inside the rear quarters and as far under the carpet at I can get but I can’t see a thing, 

 

any help massively appreciated and yes I’ve done a search

They should pass beside the wires for the fuel pump under the back seats

Nope, afraid not

theres a plug at the left side of the dash, also red iirc, they may end there on  a base model

Just incase anybody else finds this post...

 

All models should have the red plug, on some it drops down above the fuse box but on mine it was cable tied to the heater box, it looked like it had been there all it’s life

 

best way to see it was upside down in the footwell looking up, centre console removed so you can chase the wire back from the stereo 

 

cheers Fenton and Henry for the help
