got one for u guys... i heard that there are some fusable link wires in my dodge. i lead a sheltered life i guess cause never heard of it b4 any idea where they are? i'm having some trouble with my speedo, tach, and cruise. think they're related? it's in my work truck so i'm in it 12 hrs a day. there r no burnt fuses anywhere. i've checked the crank sensor wires and they look fine, as well as speedo wires comming out the back of the tranny. my batteries are having trouble staying charged so when i pull up to a job site and plug in the trickle charger it looks like an electrick dizz. i might be on to something. when anyone comments, i say it helps the milage!! any ideas would sure help. thx
