EPROM Upgrade to the DDEC on 92 Newell

[RSI Coach]

Hello all,

I am a newer owner of a 92 Newell and I'm currently running the Silverleaf VMSpc software with my coach. I noticed that I was not receiving the odometer information on the software and contacted Silverleaf for assistance. It appears there was an EPROM upgrade that was available from Detroit Diesel which had the code changes to include odometer data in the output to the software. I have recently purchased and received the upgrade kit but I now realize that I have no idea where this EPROM is located in the coach. Has anyone accessed the PROM to know where it is?
