Riddle me this... Auxiliary wiring

Progress. Here's what has been found.

All color coded wires shown in the diagram have been found in the wiring bundle coming from the relay stack. I see the wires from from the relays heading to AJ1. I think they terminate there. If I could run my own, connecting to the relays, I think I am in business. (Same for connections from J92).

Honestly, why not use this factory wiring? Makes perfect sense to do so.

 

Following this thread, as this is something I'd like to get to eventually. Seen in other threads about factory wires and had same thought about just adding OE Aux switches.

Let us know how it goes!

 

seems like theres 2 connectors in place behind the switch covers where the aux1-3 buttons would be.

would it be as simple as adding the relays in the fusebox from this point on?

 

OP, you found AJ1. Posi-tap the wires to the switches. Same for the switch illumination. Keep it out of the "environment" and running extra wires from engine bay to cab.

 

Those aren't the connectors to the Aux switches.

 

Like others out there, I do not have these in place.

 

Precisely my plan. Although, I have not found J92, yet.

 

Is that up near the top of the dash, behind the instrument display or just over the structural tube?

 

look for the connector that is bolted to the tube, it's next to it.
