I swapped a 97 body onto a 98 chassis but also swapped all the wiring from the 98 I am having some issues with the door inputs and outputs so I have a 98 dash harness for a 24v cummins instead of a 12v which mine is to swap and want to know if this will work
Expert:  Chris replied 5 years ago.

Ok, here are the wiring part numbers for the 1998 trucks. It appears as though there are about 4 different harnesses and it depends on whether or not the truck has Infinity sound system, power seats, etc. The harness should have a white tag on it somewhere. Compare the tags if you can. From what I see, it does not seem to matter if it is a 12V or 24V when it comes to the instrument panel wiring so it should work.

ok so if this is the case do I also need the wiring harness that goes across the firewall to match

Expert:  Chris replied 5 years ago.

You should use the same engine wiring harness that was in the 1998 truck and install that in the 1997 truck.

Chris

Customer: replied 5 years ago.
I did use the same engine harness. My question is there are three separate harnesses inside the cab the one in the dash, the one that runs along the firewall to the doors and the one that runs to the cab lighting, seats and rear speakers along the drivers side floor channel. Do they all have to match and what are the numbers for them?
Expert:  Chris replied 5 years ago.

Yes they should match. Let me see if I can find those numbers for you.

Customer: replied 5 years ago.
Excellent you have been a great help I just have one more question. can I use a complete 99 interior harness with my 98 engine harness? are the dash harnesses specific between gas or diesel engines?
Customer: replied 5 years ago.

I would be using the complete 99 interior including the dash

Expert:  Chris replied 5 years ago.

Ok, that would be the best way to go. This should work good. Thanks for the accept!

Chris

Customer: replied 5 years ago.

Correct, but there is a big difference in the engine compartment/fire wall harness.
