Hello guys , I'm  new to the  forum ... I recently purchase a 90 Mack Rd690s e6-300hp with 8 speed mack transmission  love the truck first Mack ever and wouldn't go back to a Pete ..need some help.. I have wiring issue and fuse panel on passenger side back dont have labels or diagram so have no idea what anything is ? Could not find any other fuse box .. not sure if thats the only one but has nothing but circuit breaker and relays No fuses ?.. also do you guys know of a very good mechanic out here on the west coast??  Thanks for all your  help . Also this truck  has no leaf spring  only solid beam suspension.. anyone know the name and capacity of it ? I thought it was a camelback but again no spring
