Im tryin to install some guages, into the dash of my pu. The guages are oil pressure, volt, and water temp, from Sunpro. The guages cost around $20. bucks each, and only the volt guage came with those little rubber groments in the U-bracket whare the two studs come thru for the + and - wires. The other two guages dont have the rubber grauments in the U- bracket, but the picture in the direction pamplet show that there should be some on the U-bracket. Will it matter since its the oil, and water guages? Painless sent me a sheet on how to wire up all the guages, because i dont plan on useing the old speedo cluster, and this sheet shows that one of the wires thats used the send the power to the guages, goes to each guage, and then you ground the guages. My ? is since theres no rubber groments on the U-brackets for the oil, and water guages, will those to short out when the power is put to them? Or does this meen that Sunpro makes a el-cheepo guage for $20 bucks?
