How do I purchase this mod kit
Ready for prime time ....
True universal 8.4 primary conversion harness (v4)... with:
- 4spd/7spd support in same harness
>> Just add our plug n play fan harness for 2500/3500 4 speed fan trucks
- Single Zone ATC part 1 built in
>> Just add our ATC part 2 harness if needed (for 14+ 1500's/classic)
- Support for Dual Zone ATC ... For those wanting to add extra blend door.
>> Will have to custom build rest of blend door wiring into add-on harness
Will be same price as current harness with ATC Pt1 built in.
That looks great!

I just completed this conversion. I had to upgrade the software on radio to 18.45.01 to be able to upgrade the maps, I did buy from u connect and had to use the donor vin to get an activation code to install version V12 it did take a long time to load.
I want to thank M2 mods for all the help and advise.
ok, I am trying to figure out which HVAC control module to get. I thought it was 68105017Ax, but I have read that it is for 2013 and not working for some. I have a 2016 2500 Tradesman with a 4 speed fan. Any help would be appreciated.
Since you are upgrading to a 2016 RA3 VP3-NA, that's the module you need for a 4 to 7 speed conversion. Last 2 letters don't matter.
Someone gave me a harness they got from elsewhere (before replacing it with ours for to problems) ...
Ours (see above):
- factory/FCA rated automotive wire
- Proper crimps/splices/harness protection
- Actual support before/after the sale
Compare the difference.
- thin stand/brittle generic 22awg hook up wire breaks easy.
- Taped splices (did solder them though)
- pins crimped correctly. I've seen worse.
* Can't fix this one.
'Someone' is apparently selling the original style 4 to 7 Speed fan /resistor harness' for 2500/3500's with poor crimps/small wire that's melting/burning up terminals at the i32A-7 connector behind the passenger kick panel. Be careful. (Would be great if that person with problem would post pictures)
