I have a 92 Kenworth W900B I am installing an Isspro R8412M gauge in. The isspro wiring pigtail is different but the #of wires is the same. Does anyone have any advice how to hookup? I have no idea which wires correspond. I haven't heard back from isspro regarding a schematic. I see they make an adapter but that is for the tach gauge.

That's rather odd, I just bought one for a 1993 W900 2 months ago. What's the last six of the vin#?

I retired from my work place, I will have to go look through the file on that tomorrow. I'm too
old and have a hard time remembering to tie my shoes let alone a obscure part number.
Sounds good, I got a reply from manufacturer with wiring for their gauge so I can get this one wired in no problem until I get oem
