I think i may have made a mistake, i bought a front end harness off ebay for my 70 chevelle thinking it was out of a 70 come to find out its off a 71. I can tell by the way the harness looks they split the wires for the head lights for the brights. Only there isnt any conectors at the end of the wires. Do i just find a conector that will fit on other head light? and use it? or would i be better off trying for find a harness off a 70?

Also this harness is off a AC car, mine was orignally a AC car but i am converting it to just a heater. Which wires will i not need? The more i type the more i think i should just get a harness for a 70 with out AC. would i be better off this way?

If it's a nice harness and you aren't interested in the TCS wires, why not use it. A couple of connectors for the turn signals shouldn't be that hard to find. May have to find a connector for the blower motor since you aren't using the option A/C harness.
