I recently bought a '68 Camaro conv. The previous owner told me that the windshield wipers stopped working. I started to troubleshoot therm and found that someone has been rewiring things. The lght bl (18LBL), dark bl(18DBL) and blk(18B) wires have been cut at the wiper sw. 3 black wires have been spliced and run directly through the fire wall to the wiper moter. An additional black wire is soldered directly to the wiper switch. I think this may be the 12 v supply. The yellow(18Y) is cut at the bulkhead conn. I suspect the switch is bad. Also, I would like to put this back together the way it should be. Is there a engine comp wiring harness available for just the wiper motor, heater blower, oil press sw, coil, etc available like shown on the wiring diagram? As wired now, they have bypassed the fuse. It really frustrates me to see "jury-rigging" like this. I just want to get it back the way it should be. Sorry for the long post, but I'm new at this and not really that swift with these wiring diagrams. Any help or suggestions would be greatly appreciated.
