94 dd problems... random lights

so on monday on my way home my water pump took a shit... its a 94 yj 4.0 5 spd... so got that fixed.. tuesday on my way to work witch is 40 miles away... brake light comes on... the one in the dash.. but is dim at first and sometime would go out or flash really fast... but now it is fully lit all the time.. so today i head out ot my shop and my speedo doesnt work... then right as i pull up the cel turn on... so i pull it in run the code and sure shit speedo signal bad or w/e... figure speed sensor.. and it also tells me something about the a/c circuit bad. even though ac was never on my jeep from the factory... but now my speedo is working when i left.. didnt even touch it.. and the brake light is on, and the up shift light always stays on now... the jeep does have abs in witch i unplugged it and pulled all the fuses and relays for..

what i have done

for the brake light i have unplugged the ebrake switch, proportiaing valve switch, brake booster switch or sensor thing and the light still stays on.. i topped my fluid off and it still contiues to stay lit...

as far as the speed sensor i am going to assume it is just a intermittent problem...

and the up shift light who knows...
then yesterday on my way back from work the shift light worked properly and the brake light went out but was replaced with the seatbelt light.. but sometimes the brake light would turn on and then the brake and the seatbelt light would both be dim...

im thinking maybe a grounding issue.

any help is apperciated...

I have an 88 And Never had the upshift light, but I have had the 4x4 light stay on for like a week! (and I know it wasnt in 4x4) Heres what I can say... I know its a pain in the ass... But you need to check all your fuses... Then there should be like actual wires running from the E brake... maybe under ur carpert to, check to make sure your wire isnt stripped at all and touching your frame.. It helped me.. But like I said mine is almost 10 years older than yours.. Hope this helps..

check those wires they must cross somewhere and be touching, wrap those and i bet that will fix the problem.. hope this helps
