The black wire with the blue stripe was likely used for the driver's
side seat switch.  You know...the thing that reminds you to buckle
up? :-)

Regarding the ballast resistor: If your '80 Spit uses a "wire"
type, it might be set up like the earlier cars.  Here's where
I found mine:

Starting at the ignition switch follow the white wire up to the
bullet connector.  The far side of this connecter has TWO white
wires coming out of it, one large and the other small.  The small
one disappears into the wiring harness and travels out the firewall
on the lower harness.  It emerges in the area near the oil pressure
switch wire<s>.  You'll see what looks like <to my eyes> a DPO
bodge...the white wire is shrink wrap connected to a second wire
here.  That wire is PINK with a WHITE stripe. Don't confuse this
color with White/Pink stripe, used elsewhere in the Spit.

Anyway...this wire is apparantly genuine resistance wire as my
Fluke sees it at 1.8 ohms for only a few feet.  From this point
the wire makes a U-turn back down the harness, through the firewall
again, under the dash and through the firewall *again*, but
now on the _upper_ harness.  My '76 Spit parts car had it
connected right to the coil + from here, but my '74 has yet
another "shrink connection" behind the coil to white/yellow
before it terminates to coil positive.  Same thing effectivly.
