What relays? In standard trim, a Dolly does not have a relay for either the horn or the J type overdrive.

I'll dig out my shop manual tomorrow, scan the relevant bits of the wiring diagram and post them for you.

I'll also try and draw up "improved" circuits to include relays, not sure how this will work yet, but I have recently learned how to work my scanner so it'll be good practice for me!

Can someone help I need to know what wires go to what terminal on the relay' and where they run to as a large part of my harness is missing
The wiring diagram I have has the overdrive connected to the power feed from the reversing light (a green wire in the transmission tunnel, if this diagram is right). As for the horn it connected directly to the horn switch on the stalk, my diagram says that should be a purple/black wire.

If you have relays, it means that your wiring has been altered. Not a bad thing, my headlights are now on relays. In that case you will just have to try and figure out what the previous owner did when they modified it.

You just use the original wiring to switch the relay on, and then run a separate preferably fused circuit with uprated wiring for the power side.

That's my least favourite past time :evil:
