I'll have to check the size, but it's the stock 1998 lesabre alternator pulley size. Should I go with something smaller? I compared it to the stock gp pulley and it's identical. Should I be using the stock gp belt instead of the lesabre then? I know the camaro's is too big.

I'm using stock lesabre plug with 4 pins and two wires. Sense wire to fuse box and other to stock ecu red.
