i'm putting a cs144 alt on my 82. my question is this adapter plug from napa all i need ?

and also do 82s need the 35 ohm resistor. i'm kind of confused.
also do i need to add a 10 or 8 gauge wire from the alt to the batt or starter.

i cant answer your questions, but i was curious why you are upgrading ?

You won't need the resistor as long as you have a functional GEN light (the light that shines in the center cluster when you have the key on, engine off.)

As for the wire gauge, well, that's a big-ole can of worms and I don't honestly know enough about battery charge rate to answer it with confidence.

i'm adding the 144 alt because i'm adding c4 dual fans.

i thought thats what you are up to .that is something that i want to do .are you getting the power for your new fans from the old fan up front?

You don't need the resistor if you have a Gen light but will still need the adapter connector to use a CS-144 with the 12SI wiring adapter. I changed my 100 amp 12 SI alternator to a 140 amp CS-144 alternator last year and the CS-144 is a great alternator, much more durable and reliable than the 12 SI and capable of much better charging at idle than the 12 SI. It was an easy upgrade. I paid $170 for a new CS-144 alternator. I have Hella Euro halogens for all 4 lights, 80/100 Watt low beams and 100 watt high beams and the 12 SI alternator struggled with charging with the lights all on at idle.

You might want the check around and see if there's a shop in your area that rebuilds alternators/starters. If there is, you can have them rework your orginal alternator and bring it up to 140 amps. I just had mine done, cost me $100 for the upgrade and rebuild.

I stated above that my 12SI was 100 amps. It was actually 120 amps and I replaced the OEM 63 amp alternator 18 years ago before switching last year to the CS-144. Upping the amperage on the stock 12SI unit is possible but not the best route to go for maximum performance since the 12SI units were never designed to handle high amperage-it can be done but the performance especially at idle will not match a CS-144 140 amp alternator, designed for that high an amperage rating from the beginning. Cooling a high amperage 12SI unit is the critical factor-the stock unit's housing will get VERY hot under a high amperage load which will eventually kill the unit.
