ok so my 2002 zx2 speedo and odometter have been cutting out. they would work sometime then not others. now they just dont work at all. i relplace the VSS and didnt fix it. so i think its a bad ground becasue the horn is also not working. but when the speedo works the horn works. now i know they have the same ground wire but i dont know where the ground is and i cant seem to find it anywhere on the net. can someone please help me.

thanks kevin

 

Welcome to the site Kevin..

Coupe? Sedan?

Main ground should be near the starter. Looks to be a couple of other connectors in line that carry the ground, and a group splice but doubt the splice would be the cause.. If it were out at the starter, think there would be more issues other than the speedo and horn involved.. Sedan appears to have a joint connector that contains the ground for the cluster out on the left fender apron behind the Constant Control Relay Module, but being a joint connector would affect multiple components like fuel pump, cooling fan ect..

 

well the cooling fan fuse blew
