might have knocked a connection loose when ya took it out, those solders are old man.

fuses / connection errors / sensors

its new connectors in the car and the gauge cluster is the same one i got the new plugs from. i cant seem to figer it out its driven me crazy. i tryed everything new cluster new harness tryed pluging them in every witch way. i check the fuse by the kick panel thats fine the only thing not working is the rpm and the turning singles i cant figer it out. any other ideas?

only thing i havent done was take out the dash again thats going to be a pain in the ass cuase now i have radio gauges and all kinda shit in there now. i dont think i have to remove the dash again cause when u take out the cluster u can see the harness and if there pluged in is there anything that has to do with the harness by the glove box side? cuase thats the only thing i cant see from the cluster being removed

is there any other fuses that has to do with the cluster besides the one in the kick panel.

try checking all ur fuses in ur kick panel,.........all of em.

from there, idk man,. rpms are linked threw ur ignitor and the ecu i believe, and i doubt taking ur cluster out would have fucked with one of those connections
