I never replaced that cable, I still have the pre LCI cable in my car.
I just bought this adapter harness so I could plug the inners in.
The instructions said to route the long white wires around to the REM & tap into certain pins but I did what Mick.86uk did from eirlier in this thread & I tapped into the same wires he tapped into, like this...
I have read in another thread that a guy who had the same adapter harness couldn't get it to work either, turned out he had a faulty harness adapter, he bought a new replacement LCI loom, coded & it worked.
I'm going to phone the dealers on Monday to price up an LCI loom as I think my adapter harness is no good. FortyThirtyFive was kind enough to message me back, he sent me pictures of his set up & looked at my pictures & also said that the harness must be at fault.
