7-Pin Hitch Wiring - Auxillary Position
From : lint radley
Q: i think the pcm problems / wiring harness issues are continuing. it seems like im getting some mistimed firing at 40-50 mph or higher. specifically when i apply the gas pedal at these speeds...maybe the problem is occuring at lower speeds but i cant feel it. spuddering misfiring etc...is there any way this is not a pcm related issue hopefully just a calibration / programming issue i guess it could be fuel but i really doubt it. any ideas shes going back into the shop tommorow... btw its a ram 1500 sport. 1998. 5.9 l v8 w/ 77k mileage. .

ywelcome for the reply. its hard to diagnose without being in the truck. to hear if its far front left right etc. the options that come to mind are wheel berrings ball joints steering linkages idler arm pitman arm and other front end allignment parts. or universal joints. the clue is low speed -- if it were transmission id expect the problem at highway speeds. well if it gets worse the mechanic will be able to find it.... i know not encouraging. -- christopher a. young you cant shout down a troll. you have to starve them. .. thanks for the reply. i find it only happens when the truck is moving. it happened once when i picked up my son from school i was parked started the truck moved up about 10 feet and it clunked twice. then it didnt happen again until the next day. it may clunk a few times and then stop and then not happen again until sometime the next day. last night it clunked about 6 times so i slowed down and it did it again another 3-4 so i put it in neutral and coasted as far as i could. when i put it back into drive i made it home with no more noise except when i parked it i popped the hood and noticed the squealing noise coming from the pullies in the front of the motor. im just praying its not in the transmission. wouldnt it be a more consistent noise if a gear was damaged other than that it shifts and runs just fine. sorry for the long post but i have no clue. thanks again stormin mormon. .

on jan 21 540=a0pm lint radley scanoma...@forwardbounding.com wrote hello ive been reading about 7-pin trailer wiring and that is an auxiliary pin on them i have been doing the trailer wiring on my 2001 dodge ram 1500. after much research i have found that the dodge factory manual simply has all the facts but they are not very specific. so i have traced all the rear wiring and made the decision to install 5 relays that are actuated by the rear wiring signals. then i will run a fat #10 12v and a fat #10 ground stranded wire from the front to the relays. then individual wires in a stranded cable to a metal shell 7 pin bargman type connector. and on to the trailer. more details if you want them. bob az .
