Rear Antilock

[Kash<(")]

Put a flatbed on my truck, put leds in for the rear lights, my rear antilock light would come on after 40mph and disable my cruise control. Put a resistor in and fix this problem but then when i would put on my lights and truck would disable cruise and brake lights. Took the resistor out to have lights again but would like cruise, Have the new rear diff sensor, Any other suggestions to deal with this?

Hi, Sorry for the lack of info. So Rear antilock would come on after 40mph, I installed Resistors and it worked for a little, then random times i would still get a rear antilock light, While the light is active o/d doesn't work also same with cruise, Thus causing o/d to die in the Transmission. Got Transmission rebuilt and the shop Struggled to get the truck to shift into o/d. Antilock light on no od, No antilock Truck has overdrive. So Digging through this website. https://charm.li i noticed the Raps Module talks to Cruise and the Transmission modules. So After getting truck back tried swapping speed sensor in rear diff to insure truck is reading correctly, Remove resistors and all the lights work great but no Cruise or overdrive. Tried installing Flasher relay no luck, Installed normal Lights and Bam Cruise and Overdrive work like a dream. So my 1990 4x4 4.0 Auto will not accept LED lights.
