Interconnecting cables and ‘Y’ harness

Interconnecting cables (A) are used to join the engine

loom to the instrument panel(s). Cables are made in

4m and 6m lengths and all cables have a male plug

(A1) at one end and a female (A2) at the other. Cables

may be plugged together to give up to 12m length,

but in general if a longer cable is required it should be

ordered as a special item, to be made in one piece.

A ‘Y’ harness (B) is available, with a male plug at (B1)

and two female plugs (B2). If necessary, more than

one ‘Y’ harness may be used, to connect several

instrument panels together.
