Yes the heater is installed under my hood right behind my drivers side headlight.

My heater has a 20 Amp fuse the the wires on my relay are bigger than the blower cables, So I am not worried about drawing too much power.. this unit is made for semi trucks and large boats, which also have large blowers.

Also the unit wont draw any current through my fuse box as the espar is directly connected to my battery, and will supply power through the wiring harness to my thermostat control.



I am trying to find out the best place to cut in the relay (See page 9 - Unit 2 (D9W plumbed with an OEM heat exchanger.))

I am trying to find out if the relay im looking for is the relay on the drives side. under the big plastic box. The relay has a fuse built into it. Correct?

Also suggestions on following back wires would be appreciated.. I dont want to puncture a hundred cables trying to trace them around my dash.

Any help would be greatly appreciated.
