Yes,
the red white wire ZI was referring to is for the 3 stage cooling fans used
with the AC instaltions, 87 and later. As for an unfused wire, the Vangon is
loaded with them including the one there now. How about completely un fused
circuits for the fuel pump or ignition? A fusible link is an easy way to
high current, save the wore fusing. Fuse links are available at your flaps,
usually on the electrical supply or HELP displays. proper link size is one
wire guage below the wire size you are protecting. Example, a 10 gauge wire
gets a 12 gauge link.  So your intaltion should go as follows:

Decide weather to feed from battery or alternator.
If from battery, beef up alternator to battery cable connection.
Fuse link
10 gauge wire.
Feed the relays
out of relays into existing wiring from dimmer/high beam switch to fuse box.
This will power lights through exisitng fuses, one for each high/low beam
each side.
Use output from dimmer switch to control relays.
