[brans72]

I found a great link to the 98 LS! wiring harness connectors and was wanting more information on what needs to be removed besides vats,air pump,egr due to LS6 intake,traction control,Air injection reaction solenoid relay output-coil,Vehicle anti-theft system starter enable relay output--coil,Theft deterrent-fuel enable feed,and maybe a/c due to having vintage air set up for my chevelle. So did I miss anything or anything above need to stay? Really need help guys due to budget here. Also wondering what you have used to remove terminal pins don't wanna cut wires out if possible. Any help I can get would be very helpful and greatful!!!! Brandon
Also wondering where to find info for splicing in a OBD2 connector please. Thanks guys Brandon
