so cal in the sgv
hey guys, ive hit a snag in my build. i was hoping for some help and i couldn't find a thread on this,

i have a 1989 toyota supra turbo. it was an automatic until i did the r154 transmission swap. i swapped my guage cluster to a turbo manual cluster, and the cluster is not the problem i changed them back and it still did the same thing. i changed the computer over to a 7mgte manual and swapped it back so the computer is not the problem. i think i might have a ground problem but not sure where. so the main problem is my tachometer, oil pressure and temperature guages are not working. and i believe that they all share the same ground. so if anyone could help me that would be great. thanks
