FD alterator swap Into S4?
 

I just bought a FD alterator, and I was wondering what I connectors that I need. I searched and didn't find anything. It has the pulley to line it up. It is a S4 JDM motor.

You need to buy a FD connector (same as s5) and wire up those two wires to the correct places. Apparently you can't use the same two from the s4 plug, just one of them. B+ goes to the same place obviously. Also, check the mounting locations, you may need spacers/washers/longer bolt to line everything up.

When I did this on my s5 everything bolted in with zero issues (other than changing the pulley)

googled s4 to FD alt (took 5sec btw):

Another way to look at it... may be simpler

Thanks.

Also, I was able to mount the alt with the belts already in the grooves (barely).... but really you need a belt that is .5 to 1 inch longer to account for the alt case being bigger and not being able to travel as low as the s4 alt. May have to play with the belt length a bit, especially if you have a strut bar.

Raksj04 I wish you had asked me. I probably have a spare S5 harness going to the alternator. Let me know if you need one and I can see if I have a spare battery harness to cut one off of.
