I Have an Alt that I aquired from the junk yard for an lt1 and I am using a 96LT1 harness. I only have a small red wire on the connector for the alt. I am hearing stories of frying alt's and overcharging, resistors etc.. I am using a 94 PCM btw, what should I hook this wire to?

thanks

 

Hook it up to a "Hot when on" wire. I didn't use any resistor and mines charging 14 volts strong. Doesn't miss a beat and doesn't over charge.

 

yours is just a 1 wire?

 

Well, the red wire is watcha need, I can;t recall if mine is one red wire, i'll reply when I take a look outside, currently in the process of moving the PCM to the stock location and cleaning up my wiring, I got 2 plugs inside the car right now and looks real nice.

 

if ya look, mine has a red wire on the 3rd pin, pin 1 being the bigger of the 4

 

Mine looks exactly like this one in the picture, one red wire:

perfect. mine too..

how's the dress up on the wires coming?

 

Excellent, its starting to look pretty clean now! I have 3/4 of the computer harness plugs back in the stock factorm ECM location, just one more to do tonight and I can put the hood back on . Im taking it to the dyno probaby in 2 weeks to see what I get and after that its off to the body shop to be painted back to the factory black.

 

good to hear. Where are you hiding the pcm? I put mine where the evap can was, that looked easier than jamming it in the dash.
My car is black now. but if I paint it, I prob won't go black. I find it hard to keep clean and is very hot. Though they do look great black.

 

Just throwing it in the factory location, its easy to get to there and its not in the way in the hood,I wanna get as much junk out from under the hood, i got my battery where my evap can was.

 

You're thinking charcoal canister. The evap canister is the silver can for the a/c.

 

Woops, brain fart.
