SPLICE THE OTHER HARNESS WIRE LEADS TO THE APPROPRIATE EXISTING VEHICLE CIRCUITS WITH THE SUPPLIED BLUE QUICK CONNECT WIRE SPLICERS (SEE WIRING LIST BELOW). INSERT THE HARNESS WIRE LEAD INTO THE HOLE ON THE BLUE WIRE SPLICER CLOSEST TO THE SPLICER HINGE. RUN THE VEHICLE CIRCUIT WIRE THROUGH THE HOLE NEXT TO THAT SO THE TWO WIRES ARE SIDE BY SIDE. THEN FOLD THE HINGED PART OF THE SPLICER OVER, PRESSING FIRMLY, UNTIL IT LATCHES CLOSED. REPEAT THE SPLICING PROCESS DESCRIBED ABOVE FOR THE REST OF THE VEHICLE CIRCUITS.
