1996 LeSabre No Parking Lights, No Dash Lights after Bulldog remote starter installed

I recently installed a bulldog remote starter on this car (1996 Buick LeSabre Custom). The remote starter works perfectly, and so did the park lights, and dash lights for a week or two. Now I have no park lights or dash lights. They will illuminate when the remote starter system makes them, but they will not work with headlight switch, which means the car is now inoperable at night! I have replaced the headlight switch (it is the kind that is mounted in the door panel and w/o traction control-FYI), and checked the fuses in the fues block underneath, and I am sure it is not a loose connection when I spliced in the remote starter (I didn't cut the wire, just stripped the outside shielding, and wrapped the remote starter wire and tapped). I am at a loss of where to check next. Any suggestions are GREATLY APPRECIATED!!!

Check to see if you crossed any of the wires accidentally. Then, check the relays.
