Tried the diff Loc and the lights came on momentarily then gone?
Thought might be a vac leak
What's the best way to trouble shoot
Been sitting so might be the pin seized
But would like to check the vac system first so finger over the end test ?
Switch seems very loose in its movement ?
Where does the vac come from on the plenum ? I Cant see it ?
Will have to check the manual but this forum has more experience than my manual
Thanks in advance
PS the wiring system in the Trakka is very sad nothing clipped or shielded all laying in the inner sills looks quite agricultural?
