I also did the Retro Shop D2S Morimoto's and couldn't be happier (except little thinner wallet). Only issue I had was the Hi Beam indicator on my dash was opposite tthe headlight. Switched pins at the blue plug and all was good. Where I drive at night the deer population has exploded over the years and this is a life saver IMO.

Thank you thank you. I had a feeling it was one of two things. Either air in the abs module where the FSM said it was necessary to run a program with a DRB III scanner to clear the air. But this light issue was happening well before I changed anything. Didn't add up. OR a sensor/ring issue that would take some travel down the road to manifest itself. I don't mind spending the cash to fix it right. I'm a believer in ABS when it works right. Even these older trucks. Has saved my bacon more then once. Thanks again, I'll update so this thread has some value going forward for somebody else.

Thanks admin for the quick reply. I've had a feeling it was something with the sensor or ring. Guess I'll get some parts ordered. As a old, retired helicopter pilot I can feel my blood pressure rise as those lights come on. Just brings back too many bad memories. Thanks again. Chuck

I've been fighting a abs/brake light issue for awhile now. When I first start the truck all is fine until I drive for about 5 miles or so, apply the brakes and both lights come on. I can clear the lights by restarting the truck and drive another 5-6 miles and the same thing. First brake press the pedal seems to travel slightly further then the second or third, etc. Here's what I've done to try to fix it. Replaced the rear diff sensor, replaced brake master cylinder (twice), replaced combination/differential valve, replaced the brake switch under the dash, had the abs module repaired by shop in Austin, TX. I've bench bled the BMC's four or five times now, also rigged up long clear hose from rear and front calipers into the bmc and used the brake pedal to bleed. I can't see any air in this system. The front hubs are not that old, maybe six years. 2-3 year old front rotors and pads. Seems odd that it takes driving a few miles down the road before the lights are triggered. If I apply the brakes every half mile or so they won't come on. When the lights are off the ABS system works. When the lights are on it doesn't. Truck brakes straight as a arrow. No pulling or other issues. I can nail the brakes to activate the ABS and it works as well as this ABS system has ever worked. Stops fairly quick. And smooth. No lockup or excessive pulsing in the pedal. I'd appreciate any thoughts on this. I hate driving around with those lights on and no abs. Only other thing I can think to do is replace the two front sensors, rotors, calipers and pads. I sure don't want to do that if I don't have to since they are only 2-3 years old. Also, FSM has a section that says there is a need for a DBR III tool to run a program where air might be trapped in the module. I've also read there is no need for this. Please help me avoid going to the dealer. They hate my 20 year old truck there. Always want to sell me a new one. TIA
