Ok so I'm wanting to install a manual high idle on an lly and can't get it to do anything from what I've read on forums on how other ppl did it so if anyone that's done it or knows how could help me out would be great . As far as I have heard and read all you have to do is give pin 6 on the grey ecm connector power and then set it with the cruise button , is that all or is there more to it ?
