I'm in the middle of 2 project.. the EFI and replacing my heater box... I SHOULD have just done the vintage air.. but that's another story.... the blower motor is new and works with direct power to it.. there is power to the fuse box heater fuse..but not to the motor... there is a connector on top of the heater box that plugs in.. that also doesn't have power.. I cant seem to find a wiring diagram.. help?? there must be a relay somewhere...
