Default Need Help! ABS and Air Bag lights are on.

This is the first time I tried to drive my car this year. Over the Winter I did the wire mod (run the wires under fender well). I also took the throttle body off and had it powdercoated, bought Moroso air intake and played around with the MAF sensor and did the throttle body by-pass. So I had all of these vacuum lines adapters off of these items and I installed all of them back today and with the many little adapters to each. I also had the battery out of the car while I did the wire mod. I installed the yellow top optima and of course the car wouldn't start. I charged the battery and fired right up.

My problem is now the ABS Light inop. comes on and stays on. Just stays on without flashing. My AIR Bag light also stays on. I turned the car off several times to reset the light but it still stays on. Have any idea why or where to start looking? Fuses to each are o.k. if I checked them all. Was it in the wire mod adapters I unplug and hooked back up?
I don't have a service manual so I need advice? I also dropped in a 160°F thermostat as well.

check your w.s.s.(wheel speed sensor) to see if any of the wire are chaffed or disconnected

Are the sensors on both sides or one? Maybe I did something to it when I did the wire mod and taking off the wheel well liner? I did move two of the three ground wires to a bolt under the fender well and maybe I didn't get a good ground and not sure if this matters to these lights?

Do you mean to unplug the PCM and plugging back up? Not sure if this is what you mean?

each wheel has a WSS and recheck your wiring and especially your grounds

I bet that its the ground. I unhooked the battery and it did nothing. There's three grounds on a LT1 right by the power steering reservoir and I left one and moved two to a bolt under the fender well. Probably should of left them together. What are the three go to? Also I painted the fender well and put one of them back to the original hole and the new paint might of killed my ground? I guess I have to take the fender well off again to move those two and check the lights to see if it helped?
