I ran mine through the firewall with the A/C wiring, and into the fuse box. Make sure you hook it up to a switched power source. (I used the acc fuse) If you have if connected to a continuous power supply, it will constantly drain your battery.
Ramjet said:I just crimped a male blade connector on the end of the hot lead and shoved it into the key on 12v connector on the bottom of the wiper motor. Just turn your key on and put the test light or meter probe up into the connector at the bottom of the wiper motor to see which one has voltage. Nice tight fit. Works great.
