Ive got the motor fired up and it runs. Ive got a few wiring problems though.

My temp on the cluster is pointed straight down to the floor, not even in the cold-hot range. I have the stock temp sending unit in the back of the passenger head.

My Tach is also not working, it is wired into the white wire behind the glove box which i believe is the tach wire.

Any suggestions/ help would be great. The truck is a 1992 k1500 and the motor is a 2004 6.0L
Thanks.
