TD5 Defender Shuttle Valve

[djam1]

I know that Discoveries are well known for Shuttle Valve failure but has anyone had this issue with a Defender?
Mine has sat unused for a week or so at a time when I go to start i after this I get the 2 Amigos.
Nanocom says its a Shuttle Valve Electrical failure, I flushed the fluid and this issue has gone away my concern is it will return.
My thoughts are I should do the modification B that everyone talks about.
The issue is that the system is wired differently so Im not sure what wire to splice into.

Any ideas

For future reference anyone doing a search with ABS /TC lights on a TD5 Defender.

The Land Rover Kits for the Discovery 2
1) Shuttle Valve Kit
2) Solenoid Block and Shuttle Valve Kit

Both appear dimensionally and electrically identical to the Defender 2002 Extreme ABS Modulator components

Dealers will tell you that its not the same but it fits and works

Oh and the famed Modification B goes to the Red Black wire on a Defender
