1986 c10 truck fuse block (secondary?) how smart are you guys?

Dec 12, 2005 0 Replies

When looking under the dash on this new truck there appeared to be a second fuse box to the pass side of the steering column....



this box had a flasher realy and 3 other breakers/relays on it. there is no reference to it in either the owners manual or the chiltons service manual... anybody know what this is, and what those breakers/realys are for?



Lastly, anybody got a detailed wiring diagram showing the connections from the headlight switch to the firewall?
