Really Uber Dumb Guy question(s) - what are these called....

[Woof]

As ET said..........................that's exactly what I was going to say

In case you are wondering what a ECM is, it stands for Electronic Cold Monitor...hahahahaha

[threedogs]

as others have said its a high idle 1200 rpm for cold mornings
well that what I use it for.
If you are stuck for the Jack cover give Gary at Nizzbits a bell

Hey Peter, aren't you putting drawers in. You might not want the jack cover thingy. I now store my jack elsewhere.

True mate, but you know how it is, you want your rig whole - neat and tidy and I figured if it was easy to pick one up at the right price, well...

Thanks everyone for your insight into (a) switches and (b) the name of the jack cover thingie, really appreciated. Oh, and I've proved there's no such thing as a dumb question, just the dumb idiot asking it....

nope
never a dumb question, I dont have a 3l, like I said, so I didnt know what the proper name or function for that switch was
and I stand by what I called it - a Jack Cover Thingy

The heat up switch cannot be used a throttle control, well on mine you can't, as soon as you put it in gear the revs drop.
It's just that, a quick warm up switch.
I think ( but don't quote me), once the coolant reaches a certain temperature this switch is in-operable / is by-passed, even if it is on.

True... 105 odd degrees

I have on occasion used it when winching others to keep the revs up and therefore the Alternator at a higher output tho

Funny buggers!

I have never had to use it for warm up, but I have considered using it with the A/C to cool down quicker.

I also believe you keep this always on when outside temperature is extremely cold where you cannot simply leave it on idle as the engine will shut down due to too cold.

Just adding my 5c worth, it only works when in neutral.
