Maybe you can answer my question, i got a 93 toyota paseo i was looking to getting a larger alternator since im pulling more power from my stereo system and what not.. The stock is a 70amp and i was thinking of going up to a 120 to 140.. what im afraid of is burning the wiring harness .. Also im not sure what the largest is can toss in it with out hurting anything either but i did find a 90 amp which i figured wouldnt hurt anything since its only a 20 amp difference and not say nearly twice the stock one. what would your recommend? i hear you need to run and inline fuse, if so how?

would this work for pcm controlled to bypass it? thanks

what would i need for my 2012 F250. I am running a plow on it and the lights dim when I use the hydraulics.

What is the function of the wire running back to the battery plug?
