Default ABS Inop and brake light on after rear swap?

got a question for you guys who swapped rear ends, I put a QP ford 9 in my car and did not keep the abs system, I just unplugged the connector, and went on about my business. I will be getting an ABS delete system but what did you guys do about the lights on the instrument cluster, the ABS inop and Brake light stay on. I have a 98 T/A is this something that a tuner can tune out or what, Oh yeah dont recommend pulling the bulb, because anyone who has opened one of these up (myself included) knows that there are no bulbs in it, just soldered LED circuits.
I know I am not the only one who has this problem right?

I took the cluster out and put black electrical tape over them. On a 98 I believe you can do something with a jump wire on the PCM pins to trick it.

Ok, for anyone wondering. On a 98..

pin 7 to pin 12 turns the ABS INOP light off.
pin 16 to pin 12 turns the BRAKE light off.

Info came from steve @ SJM. I have not tried it yet, but thanks Steve!

Negative. That only works on 98s. On mine I opened the gauge and blocked the light with black tape.
