oh wow so i could have saved myself a lot of trouble this evening tracing wires behind the fuse box and getting frustrated haha. well i used the one that went through the fuse box, oh well it still works. would it be more accurate without that connection?

also, hooked up my speedometer and it gets a little shaky whenever the transmission switches gears and then finally levels out. any way to fix this?

and also just so you guys know, these gauges were purchased from another bolter, so there are no instructions along with it.
