I plugged in my PPE HOT Xcellerator today to show a frined how it worked, and nothing happened!! Is there any way to tell if my DLC is getting power or anything? Which pins on the DLC are +12v and which pin is ground? I think i remember something about it being on the cigarette lighter fuse...? Im kinda frustrated because I need to take the truck in soon to get my FPRV looked at (been throwing P0089 and P0090 codes) and I need the truck back to stock before I can take it in...im "stuck" on the 90hp PPE HOT tune right now...

Look for the fuse labeled power point or something to that effect under the hood.

perfect, thanks Max P... Ill check that fuse, but if all fuses are good, do you know which pins in the DLC are power/ground, so I can check those with a multimeter??
thanks---Ben

Cigarette Lighter Fuse Is Blown, Push The Lighter In And I Bet It Wont Get Hot.
