i installed another wiring harness and have problems

[dinnut]

ok, i finally got around to it and pulled the old one out and put the used one i bought in. headlights wouldnt work. dash wouldnt work--like all the lights stay on constant and fuel gauge doesnt work... i tried another dash i had same thing happened.... everything hooked right up. i replaced all the fuses with the ones from my old harness and my tail lights are on constantly......???????????????? after playing alittle my headlights come on but thats it. both turn signal lights and high beam indicator stay on on the dash. i have the ground on.... what could be the problem. also, the plug that goes on the heater controls isnt right one and doesnt have the other part that plugs on the heater behind the glovebox and doesnt have the wire that goes to blower motor???? on my old on it was part of the plug that went to heater controls... anybody know what could be wrong?
