anybody out there ever have this problem after drop n in a motor?
the tach, coolant, and oil gauges do not work how ever i get the tach reading and temp on the fc commander. can anyone streer me to the right direction on this. as far as the harness location for the gauge cluster, and possible things to look for. the motor starts but the i think due to the gauges not functioning the fans aren t switching?

 

Check the ECU-connectors!

I had the same problem, seems I forgot to plug in all the connectors to the ECU!

 

all four of the yellow connectors are connected. there is a white female connector that is free but i think it if for automatic trans.

 

nope. the white one gets pluged in behind the blower motor. this goes to the dash harness. everything will work after that. there is a ground in that harness you need also.
