I have a 97 Dakota slt with a 5.2 I have replaced the pcm and ctm I got it running with a code 1492 now I have no tach,gas,elec or oil gauges when I tried the trip reset it came up with 4 #s 920,921,950,an 999? I've been checking for a missing ground but no luck

 

That's a battery temp sensor code...... (too high)

 

yes someone took that out ? is it needed?

 

Kinda. I think it has some effect on the charging system, not sure just how much.....
