between the blower motor and the resistor block (see Figures 2A and 2B for location). Tape should be used to mark off 1/4 inch on the drill bit to avoid

Cut a piece of red 14 gauge wire approximately 20" long. Strip each end of the wire and crimp a female "quick connect straight" terminal on one
end and a "ring tongue" terminal on the other end.
Cut one piece of black 14 gauge wire approximately 5" long and attach connectors to the wire in the same fashion as given in step 3.
Disconnect the orange electrical lead from the resistor block. Cut the orange lead to the blower motor where it enters the female "quick connect
straight" terminal that was just removed from the resistor block. Strip the end and attach a new female quick "connect straight" terminal to it and
connect to terminal B of the new high blower relay connector.
Cut one piece of brown 14 gauge electrical wire to approximately 4" long. Strip both ends of the wire and crimp a female "quick connect straight"
