Have a battery drain issue (.5 amp) on 99 Ram 1500. Runs thru the IOD (Ignition off drain) fuse. Traced as far as multi-pin connector under driver's seat. Appears to feed seat belt sensors and belt locks (belts lock when connector unplugged). Nothing beyond plug looks to be accessable/repairable since the belts and sensors are built into the actual seats but curiosity continues. Does anyone have a wiring schematic showing what all's running through there??? Whatever it is is responsible for .4 of my .5 amp drain.
Thanks.

if might not be exact for your 99, but it'll be close.
