I need to upgrade my glowplug controller.

The howto in the Dieselpage performance books is missing info ... like exactly which wires to connect where.

I found the purple wire by the firewall ... hot only when the ignition is on, and I have no trouble finding the ground, and the making the wire from the battery to the relay, and connecting the wires from the relay to the glow plugs.

But where do the other two lines in the '85 harness go?

Check out the "truck stuff pics" in my sig. You'll find a diagram for 85 there. The GP relay is on page 2.
