i havent used 12 core personally, max ive used is 7 core trailer cable.

What is the 12 core for? You could use two lengths of 7 core....

OK.... i got the screened 20 core from maplins.

but on cutting the origional (Kenwood) wire. this is what i found....





The cable i got from maplins is just a normal 20 core screened cable.

Any ideas of what to do

only thing i can suggest is get 2 2 4 core screen wires then a 10 core wire extend them
then tie the 3 wires together
it seems a lot of hassle but the screening is there for a reason

i think it would be best to contact kenwood cos to be honest extending the cable like u want to could cause you some problems interference wise.

Ok this is just a follow up....

After spending 5 1/2 hours on exteding the cable.. using 3 diffrent cables.
Fully continuity tested and checked the resistance wasnt increased.

Connected it up today. with no luck whatsoever

So rang kenwood for a replacement who put me in touch with Fullers (must be the company who makes the leads)

And one is being sent out for me this week. £41.95 WHAT A BASTARD!!!

Same short length so im gonna have to move them closer together now. wish i had of just done that in the first place

Did you check only the parts you extended or from corresponding points on either connector of the lead?
