Trans swap speedometer problems
I recently had my 91 Dodge 350 towed
They burned up the getrag (not NV3500) trans, so I opt to upgrade
to a 5spd overdrive NV4500
The Trans works great but the Speedometer does not.
The old one had a two wire plug, the new one three wire.
Is there a way to make this work?
I also have a new AfterMarket Speedometer that can use either but the wire diagram colors do not match and an AfterMarket VSS103 or OEM vss1 nor SC105 have any wire diagrams that I can find.
Do you know how to make this setup work?

I changed from the NV3500 to the NV4500 on my 1991 Dodge Diesel one ton.
Mine shifts better than before plus I like the ratio and Overdrive.
Problem I have is getting the 2 wire Speedometer to work with the 3 wire sender.
Does it have to go thru an ECM?
I have a new AfterMarket Speedo and VSS but no instructions or wiring diagram for the sender?
I can not get it to work either.

Sorry, I thought the Getrag was an NV3500
Now I need to change my post
My Speed Sensor wiring problem is still the same.
I need to find out how to wire the new Speed Sensor to either the old Speedometer or the new
AfterMarket one that can use 2 or 3 wires.

The 4500 is a huge improvement over the Gerag.
But I still can not figure any way to get a speedometer to work.
I have two truck manuals and neither shows what the 4 wires at the trans do.
I am tempted to cut off the old plug and try connecting any two wires to a new two wire sender. There shouldn't be more than 9 combos but it would take a lot of time to est it out.
Does anyone have a wiring diagram?
