<html><head></head><body><div dir="auto">Thanks Randall. As usual you were extremely helpful. When the new relays arrive later this week, I will follow your suggestion to use the space in the passenger footwell - perhaps using the dash facia bracket as a mounting point. The wires from the switch are already routed along the firewall behind the heater so inserting the relays there means I can utilize the feed to the front of the car and not need to run new lines.<br><br><br></div>

<pre class="blue">There is some (small) advantage in minimizing the overall length of the<br>wire, but otherwise no advantage to placing the relay near the powered<br>device. In other words, having 4 feet of wire supplying power to the relay<br>contacts, and 1 foot from relay to load; is _exactly_ the same as having 1<br>foot supplying power to contacts, and 4 feet to the load.
