66 wiring issues

[mwmeador38]

hope i'm not bringing up an old thread but i am stumped with my 66 chevy truck. when i got it the wiring harness was all hacked up. the harness to the starter solenoid was melted by the headers someone put on it so i trashed that harness and installed a new one. next i found a blue wire running from the positive battery cable going across the grill to the (incorrect internal regulator) alternator. I removed it and replaced it with a red wire running to the horn relay as the wiring diagram shows. there is currently no alternator in the truck. now when i hook up the battery i have headlights/tailights/dash lights but no horn, wipers, turn signals. when i turn the key on the gauges do nothing. is this because the alternator is out of the truck or should i be looking elsewhere. the horn and wipers and signals all worked before...
