1990 hud swap to dohc cluster issues

[Dlogue240]

I have a dohc cluster and the 3 plugs with wiring that attaches to the back of the cluster, i decided to match the wires up to the sub harness from the hud cluster and use the dash plugs to attach it all back together, after matching each wire with its matching color on the hud sub harness with the dohc cluster and i was left with 2 wires unconnected. I had a solid purple and a solid light blue with no place to go with the dohc cluster. When conecting the battery the fuel light and the seatbelt light along with a few other lights stay on constantly wile car is off, the fuel and temp max out with key is on accesory, when car is started the fuel ges back down and so does the temp when i turn the night lights on, also the blinkers both make a weird zipping noise when on and do not light up... ive been trying to find a wiring diagram for the dohc harness and the sohc hud so i can see what wires ive mixed up... if anyone had links that would be great or even if you know what wires to not match there corresponding color ive wired them to would be much appreciated.
