Needing the one in the cab myself.

I for sure probed the dash fuses and the sleeper fuses, they all check out. I don't remember any on the firewall, maybe that's what I'm missing.

Does anyone know where to start on the sleeper climate controls/audio controls? I pulled the panel off the back wall and everything seems to be connected, I checked the fuses next to storage door and in front on the dash, no blown fuses. I don't get anything when i switch on in the sleeper. The copper tubes are cold and sweating and i can get very low static out of the speakers if i crank them up. Am i missing a fuse box somewhere or I'm just at a loss as to where to start. The whole unit isn't made by mack and I don't have the truck to be able to see who made it.

Modern until you sit in them.

That's exactly what I'm hoping for.

Once it comes out of the shop, I'm sure my activity here will pick up. It doesn't seem like a lot of people out in the real world know much about these things and Mack seems to keep the info under lock and key, lol.

Thanks.

Thanks!! seems like a great community.

See, the 427's torque starts dropping off around 1200 rpms though and the HP starts dropping off around 1500. Just seems, it'd be better to pull all the way through the range instead of topping out. TBH, looking at the graphs that were buried back in the threads, the 427's torque curve isn't flatter by much and there's only about 100 LB-FT between the 460 and 460XT.

Anyone know if any of this is still an option? I've gone through topics but they're a little old. Looked at Rochester but if I can just update the programming it seems like a safer route. Is the "used ECM" still the way to go?

I have a 99 CH613 with an E7-427. Unfortunately, it's been in the shop for over a year due to numerous circumstances. Anyway, glad i found this place and it's already been worth the time to sign up.
