I have a 08 L92 with corvette front drive assembly .This is going in my 87 Monte Carlo SS.My question is do I need to install a resistor inline of existing alternator wiring?I have 1 wire existing from my original alternator harness.I have factory voltmeter gauge and dummy charging light.Was going to hook existing wire up to L terminal on harness coming out of Vette alternator.Any info would be appreciated .

Might work. See if the wire from the "dummy" light has 12vdc on it when the ignition is on.

Should work the original brown wire has power with key on and your gauge should work ok

I just have 1 single red wire from my 99' connector to the brown wire, no extra schtuff. Aftermarket voltmeter works fine.

Looking at my ALLDATA, your car has either a charge indicator light or a voltmeter. Not both. So if the car has a voltmeter, the brown/white wire is a resistance wire. That will go to the L terminal of the alternator. If the car has a charge light, hook it up to the L terminal. You will also need to hook up the S terminal of the alternator to the battery terminal of the alternator for the charge light to go out when the alternator is charging.

I thought I also had a light on the right side of my dash along with the other info lights that are there.I'm hoping to try to start this up this weekend and didn't want to cook alternator.Thanks for all the info.
