Engine loom

[darrenjlobb]

Modern style plug with yellow end is oil pressure switch.

Black 4 pin one is the pump immob plug, one of those wires (normally red one) is ign live, connect just that wire to the top of the stop solenoid.

The ring connector could be few things, cut bit of your insulation and tell me what colour the wire is... If its green / yellow its ground, if its a thin wire, its the alternator exciter, if its white and thick (think this is most likely) its either your glow plug rail feed, or the glow plug relay feed, which connects to start for its feed (same terminal as main battery feed wire)

Plug on rad is basic 2 level heat switch for ph1 looms for fans, looks like you have a ph2 loom going on there, so not sure how that will work as the fans are controlled by the ecu box under the chassis leg on a ph2, using the temp sensor on the stat housing...might be easier to just relay it / manual switch if you get problem / wire in that rad sensor to a relay...

Brown connector looks like water in fuel sensor, sometimes located on rear of fuel filter hosing, but often not fitted so redundant, anything else?
