So you have ARB air lockers installed in your Land Cruiser. Yay! But now you have these three ugly Carling-type switches that stick out of your dash like big, out of place, plastic pimples in your otherwise pristine dash. Well, as it turns out you can actually eliminate two of those eye sore switches and use an OEM "lust worthy" locker dial instead and use it the way Toyota intended.
This basic wiring kit includes what is needed to convert your switches to OEM dial and keeps it as plug and play as possible. You do have some cutting and crimping to do to finalize it. OEM connectors and terminals are used to produce this piece.
• (1) OEM 80 series locker dial (84725-60020)
• (2) OEM combination meter light bulbs (83120-60020)
• (1) OEM harness connector (90980-10631)
• (3) OEM switch terminal pigtails (82998-12170)
• (2) OEM dash terminal pigtails (82998-24180)
• Pre-wired harness
• At the ARB locker solenoids:
The pinouts of the two wires going to each of the locker solenoids needs to be swapped. The terminals have a small metal tab that can be pressed aside using a terminal pin tool and the terminals can be pulled out the back of the connector. Both black wires needs to go at the top/wide-end of the connector "T's" and the yellow and dark green wires need to go to the bottoms of the connector "T's" respectively.
The small black wire going to the small two wire (black and purple) connector that feeds into the compressor needs to be cut as far away from the compressor and as close to the wiring harness as possible. The end going into the harness needs to be capped off to protect it from shorting out. This is done by placing the supplied piece of heat-shrink over the cut wire. Half of the heat-shrink should hang over then heat the heat-shrink and pinch the end of the open heat-shrink to get the adhesive to adhere to itself. The black wire going to the compressor then needs to be crimped into the supplied black ground wire and connected to a ground source.
The ARB compressor's "isolation" switch is now the only switch that will be used. The red wire with yellow stripe needs to be connected from an ignition 12v+ source directly to pin-2 on the compressor switch. The solid red wire needs to be connected to the black and red wires at the four wire (dark green, black, red, and yellow) connector and then connected to pin-3 on the compressor switch. The blue wire with a white stripe needs to be connected from a dash illumination source directly to pin-6 on the compressor switch. Pins-7 and -8 on the compressor switch need to be connected to a ground source.
Remove the instrument cluster from the dash. Insert the two light bulbs into the front and rear diff lock indicator light holes in the back of the instrument cluster. You can locate these by holding the combination meter to a light source to see which are the ones for the lockers. In the wire connector that is farthest to the passenger side behind the instrument cluster, remove the two plastic inserts to gain access to the terminals. Remove the terminal with the white wire at position 10 and replace it with the pin on the red wire of the supplied harness. Remove the terminal with the green wire with a red stripe at position 9 and replace it with the pin on the blue wire from the supplied harness. Protect the two terminals you removed from the connector before reinstalling the instrument cluster by wrapping with electrical tape separately.
