Here's the truck on jackstands to verify the diff is locked.
Okay, okay, so I got lazy...
two jackstands and the jack under the back pumpkin.
Here's where I mounted the lit rocker switch.
The relay I used is Radio Shack p/n 275-218. DPTP relay,
12VDC/10A. The Diff Lock Control
Unit is fused upstream by a 10A fuse, so a 10A relay is large
enough. I wanted a DPDT relay to
maintain the circuit in the original orientation when not in
use, for two reasons. 1, all the control units check
all their switches and sensors regularly, communicating via
lan/can. If I'd isolated the diff lock solenoid
from the DLCU, there'd be a malfunction lamp. 2, both ground
and power are routed through the DLCU,
so I'm betting it's able to isolate both, meaning I needed to
supply both ground and power for a complete circuit.
