any body know why is that happening?

when I rev the engine the odometer is jumping

 

Water in the connector?

Try drying it out and putting some dielectric grease in there.

It's located on the transfercase.

 

i just wanna say thats neat!!! but i dont have a clue what it could be. maybe a connection like overland said? they are all moved by electro magnets on the back of the tack and spedo though. so maybe a wire is loose or touching or something on the back?

 

thats funny lmao
