Here is the wiring for Honda using the 4pin Denso
L = Ignition lamp
IG - for Ignition switch protected by15A fuse
C - goes to computer then back out to ELD (Electric Load protector)
B - (recharge wire) goes to battery protected by 15A fuse
FR -goes to computer.
the numbers on alternator plug should be ;
1 = C
2 = IG
3 = L
4 = FR
Hopefully this can give you a basic idea, but since you do not have the Honda wiring on your ride, perhaps these Denso schematics applicable to Toyota can help in a vague way...
Just use the wires needed to connect to function, no need for the computer crap as per Honda.
