USDM vs. CDM Alternator
ok.. i know came cross a problem with the wire issue with my alternator
i checked the engine harness plugs it tells me USDM 4 wires/CDM 3 wires
so now this is what i need to know
the alternator i have is the 3 wires design and the plugs i have has 4 wires..
USDM
1. Blk/YEL
2. WHT/GRN
3. WHT/BLU
4. WHT/RED
CDM
1. WHT/RED
2. BLK/YEL
3. WHT/BLU
so basically what i did was i wired them up to the CDM spec and left WHT/GRN alone on the side...
now car starts fine.. it charges the battery as well but my dash lite for the battery stays on, how do i kill it?
i found out that the WHT/GRN i left is ALTC(Alternator control) which sends alternator control signal out... if i switch it from WHT/BLU to WHT/GRN would the problem be fixed? i do not want to mess with my wires even i already did.. but i am hoping someone who knows this can help me out
thanks a lot

I do not have any experience with Canadian alternators, but I <u>can</u> imagine legitimate reasons for Canadian cars to have different alternators.
If I were you, I'd buy the manual, visit your local Acura dealer with OG mechanics, or I would contact the guys at A&J Racing (who would be very acquainted with differences between Canadian and USDM cars and the associated cross-referenced parts problems).
