just did a motor swap its a 93 usdm shell with a 94 jdm motor and harness now instrument cluster doesnt light up and only fuel and oil pressure works please help thanks!

 

check ground to the cluster

 

where is that do you happen to have any picsa of it?

 

you most likely missed to plugin the white connector off the harness.. its right before the set of connectors for the ecu..
i would assume the odo works with the key on but doesnt when she is at idle started.. if so... its that connector

 

I actully dont haveit pluged in but i checked the fsm it said it was for the emissions to dash. Anyways if that is the problem can anyone shed some light on this issue because i swaped a jdm motor into the car and the white plug that your talking about is too small to fit now any help would be great thanks
