Thread: Would anyone know what theses wires are?

Without more info...

Does your D2 have CDL? Does the light come on on the dash when you engage it?

Tombie has a point here, they look exactly like the plugs for the diff lock switch on early modells, connect them together with a paperclip for test and turn ignition on, if the diff-lock warning will be on it means that's it... which is very likely

If it isn't for the CDL it may be the spare connectors for the NAS spec TC interlock solenoid. Not fitted in Aust.

Thanks for that when I get a battery back in it I'll get a spanner and turn the cdl and see if light comes on if it doesn't I'll try the paperclip on the wires.


Hey sierra, thanks for that tip the other day about the depression valve, went to do egr removal and previous owner was a bit sneaky (left the egr body there but blanked off the exhaust side with a plate between pipe and manifold ). Glad I decided to pull it apart though as depression valve must have been gone for a while as there was a pool of oil sitting in the hose from intercooler to inlet manifold and inside of inlet manifold looks like this , the hoses hadn't delaminated but were very soft so silicon are going on anyway since its all going to be pulled apart this arvo to clean intercooler and inlet manifold

I don't see well what colour is the trace on the black wire, if it's blue it's certainly diff lock, if it's green it can be tranfer box temp sensor wiring too which is also for NAS V8s, so if the transmission warning comes on with it bridged then that's it... the interlock solenoid wire is green with purple trace and in the pic it looks like some black wire with a trace

I did the same to mine completely removed the egr and all the black/blue smoke stoped I also put a oil catch can on and no more oil in my turbo pipes, have to empty the can once a month make sure you block of your vacuum pipes and un plug the vacuum manifold I forgot to do that on mine and the car would not run

paper clipped the wires and they are tranny temp, locked the diff and no lights came on so they are disconnected as well, will look for them later when I put lever in for it, thanks for the advice
