Alternator died today... and want to use a new one i have which is obd2. I have a 91 ef8 crx and noticed it only uses 3 wires instead of 4 on the alternator plug. I was wondering if the newer obd2 alternators need that 4th wire or not? I did do a search but my wire colors are different then the regular 88-91 Civic/Crx colors. On my obd0 plug i have blue, red, and White/blue. On the obd-2 plug i have white/blue white/green, black/yellow and white/red. If anyone can lead me in the right direction that'll be great. Thank you.

I am going out on a limb and saying if the connector is the same from the 3 to 4 wire alternators...it should work...

 

Thats a pretty ignorant assumption, at my cost. If you don't know..don't reply, i don't have time for guess work.

 

Geezus people...help a **** out here

 

There is 2 ways you can go about this if the color adds up for the position of the wire for the black/yellow white/blue go by the positions of the wires and match them up...if not try white/yellow with white/red and of course the other wire with blue...

or get a manual out and start looking...

If this by all means needs to be done asap...give Rywire a call Monday...cost you maybe $1 for a 30 second phone call...

Just wanted to thank you.. I just converted a obd 1 alt. to a obd 2 harness....

Good find.

 

make a good diagram possibly with a picture of the plugs and the conversion...and post it here for the next person wondering how...

 

this works too in most cases
