Jeramie below are some pics of 128 4 cylinder layout that is the same basic wiring harness as the 130 6 cylinder . The main cable from under the dash goes down the right side to the junction block and than branches forward and rear , forward to the generator and lights up the in side of the radiator shell , the rear to the brake light switch at the base of the peddle and than to the tail light ., as this is a right hand drive car all goes down the right side . For left one would expect that your harness would come out through the firewall to the junction block headlights forward and brake and tail light wire would go down the left side . The Master Parts Book show listing for left and right harness .I suggest that you lay the harness out on the floor as a trial and check the position of the wires , its a simple harness ,not that much in it .
