A few quick questions for ya, guys. I have a 1999 Ram 3500 v10 that is getting a 5.9 12-valve Cummins swap next week. I have a complete 97 2500 Diesel donor vehicle. I plan on swapping the complete fuel system & all the electronics forward of the firewall. So here are the few questions:
1. Is the 99 cab wiring compatible with the 97 engine compartment? (will the plugs work?)
2. I have picked up a 01 Guage Cluster from a Cummins. Will this work with the 97 Wiring?
3. Should I change the brake booster from the 99 model to the 97 vacuum system?

If anyone has done something similar to this let me know. I'd appreciate the help. Thanks guys.

 

i think your going to have to use the whole wiring harness out of the 97 and change over the whole vacuum system too and the gauge cluster i am not sure and by the way welcome to diesel bombers

 

Thanks for the quick reply & thanks for the welcome.

 

i am going to agree with redneck but cluster will not work you will need earlier

 

Ok... here's another question for ya, guys: Will the front coils from my 99 V10 1-ton dually be heavy enough for the cummins? Or should I use the 3/4-ton springs from the donor truck?

 

the 1 tons should be fine IMO, you can use a gas cluster as long as it is 94-97 with the mechanical odometer. i have one out of a 96 gas truck that will be going in my 96 Diesel, main reason is the stock tach stops at 4K, the gas runs on up there not that most people will need it or anything.....i would do the hydroboost setup if it were me, vacuum leaves alot to be desired on the brakes. also i don't think a pre98 cluster is going to fit in that dash perfect, i have never compared any side by side.

 

In doing some research to see if my gas cluster would work, the v10 cluster that are in 98+ trucks would work, you would need a wiring harness and pcm out of a early 98, but they are hard to come by.

 

ya i meant to put that too, but like you said finding the harness and comp from a 98 12v in a junk yard is like trying to find a needle in a haystack.

 

Well, Kudos to my Mech Randy. The Cummins is in the 99. Truck runs, wiring complete with the exception of under-dash. Brakes done, used the Hydro (thanks for the advice on that one). Should be on the road by Tues, Diesel-Gods willing. I need to get back to work. Using the factory donor truck guage package with a little mod to the 99 dash bezel.

 

Ok... here is the in's & out's of the transplant so far: Drove the truck today for the first time with the 12v in it. NONE of the 99 wiring works. scrapped everything with the exceptions of a few connectors. The 99 ram is sporting 95 (not a 97.. snafu on my part) wiring, fuel lines, heater core & almost everything else. Tried to use the 99 dash, but it was cracked to begin with & imploded once out of the truck. Didn't matter anyway, had to use the 95 dash due to wiring & switches. Using 99 column though. For some bizarre reason, nothing on the orig. 95 dash is working even using the 95 harnass. I must be missing a relay or something silly. Should have the truck back together & on the road tomorrow afternoon. (I sure hope so... 2weeks off work is killing me.) ----> OH! And I need an AC-heater switch from a 94-97 (Diesel model preferred, but not necessary... so if anyone has a dead truck lying around.. please, let me know what you want for it.)
