I actually like that. Warning lights are a very good idea for the reason you just stated. My factory water separator is long gone (and I wouldn't use it anyway) so maybe I will contemplate installing a low oil pressure warning switch at the turbo feed and wiring it to the WIF lamp.

 

That makes sense, problem is where they put the lights. You're not supposed to be staring at your feet while driving.

 

Well, while we're slightly hijacking Jan's thread, an update. I now have a tach! That yard came through; I found another truck in another of their yards with the right dash. Dude I Emailed followed up, confirmed it's the right thing, sent it out no extra charge! All-around better shape (sharper lettering, etc) than my dash, so rather than swapping the circuit board, etc, I just used the whole dash. And double-bonus, it has a trip odometer.

Some minor mods, same as I did on the old dash. Painted the needles fluorescent orange. And create about 1/8" space between the mask and main panel, using nuts as spacers. Also use EPDM foam strip to surround it, and between the compartments for the indicator lights. This allows the green illumination lights to flood more light on the dials.

Alas, this newest dash that came didn't have a lens, and both the other dashes are no trip-meter, so no hole in the lens for the reset button. Also, there was no actual button on the reset trigger on this dash. But I didn't want to give up that trip meter. So, I found some wooden dowel (3/16", maybe?) in the basement, cut off about 1.5", "painted" it with a black magic marker. Cut a slot in the end to wedge it onto the trigger. Eyeballed a location, then drilled a hole in one of the masks. Works and looks pretty-much factory. And plenty of night illumination:

That's with plain-old old-school tungsten peanut (194) bulbs.

Oh, and a little reverse sticker shock. After seeing them go (or not...) on eBay for $200, $250 or more, and the last "affordable" ($100) one being sold out from under me, I got this one for $65 WITH the shipping.

 

That looks great madpogue. Glad you finally found a tach and for such a bargain. The illumination looks great. I might have to try that, mine was always horribly dim. I read the bulb covers darken with age making it a common problem. Yours looks much improved! The trip odometer button is built into the lens. There is just a flat disc the contacts the lever on the speedometer. Your home made solution looks pretty good though. If I find a decent trip odometer lens I will keep you in mind.
