hello again, i have a 1986 daihatsu rocky 2.8 diesel non turbo and i have asked this question before but i still haven't heard an answer or find it in the search box so any help would be highly apreciated, i cant seem to find the glow plug light in my dashboard, where is it exactly unless its only the relay click. i look carefully in the dashboard and i only see the three rectangular lights on the left wich indicates oil,battery charge and oil drain (by the way whats the oil drain light for) than on the center you got the speedometer with the high beam indicator underneath and the tachometer and final you got the parking brake light on the right with two more on top but there is no light bulbfor it on the back of it. please advise thanks.
