Mine is a V Mack II i pulled the computer out.

I have a 1997 CH600 V Mack II with a wrecked cab. Where the wiring harness plugs in on the firewall is two round plugs. I bought a cab (without seeing it first) that is the same year but where the wiring harness connects on the firewall is rectangle. Is there an adapter that will let me hook them up without having to change the cab wiring harness?

I have a 2020 Mack Pinnacle. Truck has been deleted and runs good at times with boost pressure of 40+ pounds, then all of a sudden the boost pressure will drop to 20 pounds and won't build above that. Driver can pull over cut the truck off and restart the engine and it may run fine for 5 miles or 100 miles. I know of some other guys having the same issues of low boost pressure. Anyone have any ideas of what the problem could be?
