So there should be a 40 second timer for the glow plugs? I don't think mine is working. I'll have to verify that with a stop watch next time since I think the glow plugs are staying on indefinitely in key position "2".

I didn't know there is an "aux" key position. One mine, position "1" just unlocks the steering, no accessories. "2" enables cig lighter, radio, Pwr windows etc. and is what I think is the "aux" position.

btw, where is the accessory relay located? I hope there is one.
