Alright i read the 2nd gen alt in 1st gen thread and did not come to any conclusions, Will a S4 TII alternator work in an -SE?

rotor vs. piston

My sources say yes

I figured so, but i just wanted to double check.

Direct swap. You may need to thin the large shim, but that's it.

OK, here's the latest of what I have found after doing this conversion three times in various year's chassis. For those wanting to ditch the 50/55 amp alternator in your 1stgen, this is probably the cheapest way to kick up to an 80 amp alternator which should be plenty unless you've got a TON of stuff and you run it at max ALL the time...

First up, the universal wiring diagram reference...

For the TII alt plug, I've seen two different wire colors, but I think the yellow w/blue stripe and white w/green stripe combo may have been a conversion harness leftover itself. Underneath is a quicky reference to all the different color combos I've seen in the various chassis and the physical rlationship of the different plugs...early style on bottom. Just match your colors and you'll get it right. I need to state again that the 1979 part had already been converted to the later style charging system and the external regulator was eliminated. Since the car is gone, I really am not sure what is involved making the conversion, but these are how the wires in the engine bay harness attached to the TII alt when I replaced the old alternator originally installed by Rotary Performance


Going from the top green arrow clockwise...
The '89/'91 TII plug itself which you must have gotten with the alternator to make this happen.
Tiny bit of the blue stripe on the yellow wire from the TII alt plug....the second TII alternator I got for the '83 had simply yellow and white wires with no stripes at all.
White wire w/black stripe...note that this particular wire's color scheme seems to be the same regardless of year...looking at the Haynes, you wouldn't think it so, but neither of the swapped alternators ever burned out.
8 ga. wire going to the fusible link box on the strut tower of the '80...it never, ever gave me any problems with this routing, I might add.

This is the actual install into the 83 chassis...

For this install, I decided to completely take apart the plug of the TII alternator I picked up and run the '83 wires directly into the TII plug's metal spades...a lot of frustrating work because of the small size of everything, but the result is a completely factory look...the wire on the output pedestal this time goes directly to the battery, which is the method favored by Rotary Performance as evidenced in them doing just that to the long gone '79...

yep, it's easy as putting shredded cheese on pizza. just take that shim and grind it down.
