LOL but to answer the original question..lol Yeah, they all function, the oil pressure resets to Zero if you just turn power on for a sec after the engine is off. So I suspect it will work correctly. Ill pull the trigger on a decision tomorrow Im more that likely going with Plan D and just run the vortec sender as simply a sender. and leave the OG switch, just trim the 1 tan wire I need to lengthen. Whats funny is I bought a little Mitsubishi tractor, and after I bought it, It was used of course, I would notice the temp light would start out dim and just get brighter, found first off there was no T stat so i rigged one up from a gm 3800 , but i suspected someone replaced the switch with a sender , so I just swapped my switch in place of its sender and used the tractor sensor in the pontiac..lol works perfect.
