There is a place on the oil filter stand off that you can tap into (put a T on it to run both sending units. A guy with a 3.2 in a Rodeo used it for his oil feed for his turbocharger and I've seen it under there. I was thinking about doing it on the a-pillar but they don't make an exact mold pod for our pillar so you'd have to use one of the universal ones and sometimes they can be a pita. And superboom, no tube needed, using an electric sending unit so no oil actually running into the truck. And for nitrous, check out the gauge panel I made for my old 98' Z71:







arming switch with warning light, button for purge, and switch for bottle heater

I'll get plenty of pics when I get it installed, I'll snap a pic of the new radio position tomorrow
