An Update,

Sorry been so long, been busy with working, And put it to one side, Until saturday morning when the gear linkage played up, Quick visit to the breakers and £5.00 gave me a replacement linkage, And its bang on

Anyway back to where we are, I have found the reversing light switch on the front of the box, And the connection, Help from another thread on here, So how do i test it by bridging the 2 wires out ? Does the ignition just need to be on or engine running ?, If that works then all i do is simply get a new switch yeah ?
