IMPORTANT:
Be careful not to short power and ground circuits by touching the two jumper wires together. If circuits are accidentally shorted, the PWR ACCY (30 AMP) circuit breaker in the convenience center will probably open. Should this occur, wait until the circuit breaker has cooled and closed to continue procedure.
3. Backprobe two-way connector C304 (B) terminal "B" (BLK wire) with a jumper wire (D-SOLID). Connect other end of jumper wire to six-way connector (A-motor side) terminal "D" (RED/GRN wire) (Figure 1).
Forward/back motor will begin to operate in the BACK direction with jumper wires connected. Allow motor to operate until seat is in the full BACK position.
4. Front height motor test jumper wires from six-way connector (A).
5. Connect jumper wire (C-LONG DASH) from two-way connector C304 (B) terminal "A" (ORN/BLK wire) to six-way connector (A-motor side) terminal "E" (YEL/BLU wire) (Figure 1).
6. Connect jumper wire (D-LONG DASH) from two-way connector C304 (B) terminal "B" (BLK wire) to six-way connector (A-motor side) terminal "F" (RED/BLU wire) (Figure 1).
Front height motor will begin to operate in the UP direction with jumper wires connected. Allow motor to operate until front of seat is in the full UP position.
7. Rear height motor test jumper wires from six-way connector (A).
8. Connect jumper wire (C-SHORT DASH) from two-way connector C304 (B) terminal "A" (ORN/BLK wire) to six-way connector (A-motor side) terminal "A" (YEL/WHT wire) (Figure 1).
9. Connect jumper wire (D-SHORT DASH) from two-way connector C304 (B) terminal "B" (BLK wire) to six-way connector (A-motor side) terminal "B" (RED/WHT wire) (Figure 1).
