I need a manual with wiring or just a wiring diagram for a 98 Ram 3500. I have tried the search function and have not come up with anything. I can't believe there are none online for a 13 year old truck!

 

There used to be a website operated by a disgruntled Chrysler employee with parts manuals and wiring diagrams but Chrysler sued him to take it down.
Seems that Chrysler is very protective of their data.
Buy a factory service manual for your year that has over 500 pages of wiring on CD for $35 here> http://www.genosgarage.com/products.asp?dept=241

Beware though the '98 FSM is really for the '98.5 24 valve.
There are lots of things that are different.
Unfortunately '98 is sort of an odd year, unique to itself.

 

Could you use a 97 manual? I don't know how mutch the trucks differ between 97 and 98 (not 98.5) but it may cover it. I should buy one because I am using my dads 95 manual.

 

"One of our best selling items is the Haynes Repair Manual for the ‘94 - ‘01 pickups. The staff likens this manual to the "Cliff Notes" used by students in lieu of reading the entire book."


That would indicate to me that the cd is just highlights and not everything.

Plus I don't thin Geno's is a subsidiary of Chrysler and he has the manuals, I am guessing reprints. I just have a major problem paying well over a hundred dollars for a manual for a 13 year old truck.

No, the CD includes the entire 1200 page manual with nothing omitted.
But like I said '98 is an oddball.
It was supposed to have a24 valve engine but it wasn't ready to go on time so the wiring is a mix of 12 and 24 valve. You almost need to have both a '97 and '98 manual to get it close.

Genos buys it's manuals and CDs from Chrysler.

 

In that case I will get the CD.
What I am looking for is how to hook up the trailer relay, mine is hot all of the time but there is a relay in the box marked trailer relay which is not hooked up to anything I can find.
