Though the FE3&#8217;s tube runs around the back of the block, so some modification is needed to end it near the heater core inlet at the firewall.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone\" title=\"FE3 Miata heater core feed line\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/motormount2.jpg\" alt=\"\" width=\"600\" height=\"398\" \/><\/p>\n<p>In my case the mod included cutting and welding to get the hard line up high, away from the turbo downpipe. The lower line was originally a piece of hard tubing connected to the core and head with short pieces of hose.<br \/>\n<img decoding=\"async\" class=\"alignnone\" title=\"FE3 Miata heater core feed line\" src=\"https:\/\/fe3miata.com\/site\/wp-content\/images\/FE3v1-gallery\/images\/cooking02.jpg\" alt=\"\" \/><\/p>\n<p>The connection at the rear of the head was post thermostat.

I removed the stock thermoswitch for the fan, handing over fan control to the ecu.
