Cluster wiring

Found out why my gauge cluster wasn't working right. The cluster and dash are from a 88, and the car and harness are from a 91 so they wouldn't work together. After some research online I found I could just de-pin them and re-pin them the same as the old 88 wiring harness I have. After extending 5 wires, the gauge cluster works fine. There was one wire left over but its just the seat belt indicator light which I really could care less about.
