so i thought... oh. probably a ABS Wheel sensor.... she drove fine home... went inside got my TechStream laptop and plugged her in... spend the next 5+ hours trying to get them to talk but no bueno.... while idling trying to get TechStream to work... the car starts freaking out... every light on the dash lit up like it was a Land Rover, Tach started bouncing, the gear indicator went blank, Range and outside Temp displayed 'E'....... I'm stumped. I have no idea what's going on

unplugged the battery overnight, put a trickle charger on the battery so it was fully changed, cleaned all the terminals, unplugged ALL my aftermarket accessories, unplugged my aftermarket LED's, unplugged the ABS Module (Just to get it to stop freaking out), checked every fuse with a multimeter, found a lil water inside the tow trailer plug, cleaned that and took out all the fuses and relays associated to it.... I can't figure it out

ANY input from you guys would be greatly appreciated...

Could this still be a friggin speed sensor spazzing out the ECU's???
