I'm installing a Viper 150 ESP. I'm trying to figure out the PK3 module wiring to bypass the factory Passkey security system. Below is the wiring list on the back of the module, and I'm using the Grand Prix wiring site to try to figure out what to hook up to:
Red -- 12V+
Black -- Ground
Blue -- (-) Remote start
Green -- Key Sense
Purple -- Data (I/O)
Pink -- IGN (ECM side)
Pink/Black -- IGN (Key side)
Blue/White -- Fuel Enable
I was able to get access to another Grand Prix that has the same remote start system installed. So I copied the wiring for the PK3 module.
After finishing the wiring in the 2000 GP, I tried starting it w/ the factory key to make sure the car still ran. It started and ran fine for minute or so before I shut it off. Then I removed the key and shut the door. I waited until the interior light went out, and then I was gonna try remote starting the car. However, when the interior light went out, the headlights came on! I tried remote starting, but nothing happened.
Then I noticed smoke under the dash, coming from the PK3 module. I unplugged it, but it smelled pretty burnt. I may have fried it.
I tried starting the car w/ the key again. It started, but only ran for a couple seconds before stalling. I ran a jumper wire to reconnect the pink ignition wire, and after that the car started and ran fine. So that tells me that I cut the correct pink wire.
Based on the symptoms, it seems like I probably connected the wrong ends of the pink factory wire to the module. But I triple-checked, and I know that the end of the factory pink wire that goes up into the steering column was connected to Pink/Black -- IGN (Key side). The other end of the factory pink wire connected to the large junction block deeper under the dash, and that is connected to Pink -- IGN (ECM side). So what's the problem??
