As for the vacuum line. It doesn't matter where you T into the line. You need to be hooked in anywhere on the horseshoe of line from BCS to FPR to LIM to MAP. Doesn't matter a bit where in that line you tap in. Not sure why Blueguy was pushing you to put it in a nice clean location vs making a mess under the snout.
which fuse is the heater circuit fuse? underhood fusebox or in car?
