Ebay GT45 + 5.9 Magnum + E85 blow thru

Ok subcom got a few questions for ya. 1st my 2 step doesnt seem to work, I got the ac wire hooked to the positive side of the brake pressure switch when the brake is pressed so 12v going to the ac wire. I have the ac disabled in the ac setting is there something I'm missing. 2nd when you narrowed your rear end did you notice your rear shocks are almost bottomed out when you mounted them back up, my car seem to bottom the rear end out now that its been narrowed. If you can post a pic of your shock that would be great.
