long story shirt, i did the 411 pcm swap, had it tuned for electric fans, i had 2 16 inch electric fans sitting on my back seat but someone broke into my truck before i could install them, im about to order 2 more 16 inch fans but i am a little uncertain about the wiring for the relays, does anyone have a wiring diagram they can upload or send me a link to, thanks
