alright, so heres what i have, i bought a 1999 dodge ram 2500 4x4 5-speed with a "12 valve" though..... runs and everything, drive it fairly often, BUT the tach doesn't work, oil pressure, or the water temp. so i was thinking that if i got a 1998 12 valve engine and transmission harness with the PCM from a 1998 if that would fix things. PLEASE help......HAS ANYONE DONE THIS or know what i can do :/

 

you may have to get the gauge cluster from the 98 too...

 

So if I switch all that then I should all work?
