ef wiring nightmare !!

so i replaced my heatercore and it required to take out the whole ------- dash in my 90 hb, well i got the heatcore all back in there and the harness all hooked up but now NONE of my interior lights work and gauge cluster throws a cel but i checked the ecu and there's no code, if i turno on the blinker or the lights the cel goes away!! ?? what the ---- cause's this p.s. nothing interior works i.e. heater blower, tach, temp, whole gauge cluster except cel light, i tried replacing the cluster and get the same thing, is this possibly a ground or is it maybe the intermidate switch ?? anyhelp appreciated, also what needs grounded and does any one have the color codes of the interior wiring?

Ground.

Download one of the manuals, flip to the part where it lists all the Gxxx grounds.
