I decided to put this thread together for anybody wanting to wire Harrop E-Lockers into an HDJ81 or FJ80 using the OEM locker switch and locker dash lights. I found most of the info spread out over a couple of other 'Harrop" threads and wanted to put it all together in one place and add some pictures and diagrams.
I will not be focusing on the actual locker install or setting up of gears. For that I simply removed my 3rd and shipped it to Ken (AKA Zuk) at Toyota Gear Install Harrop He also supplied the Harrop locker through Cruiser Brothers @wardharris
Parts needed:
Harrop Locker(s)
OEM locker switch: 84725-60020
OEM Bulbs x 2: 90981-11018
OEM Bulb Sockets x 2: 83101-14040
OEM Terminal repair wires x 3 for 1 locker, x 5 for 2 lockers: 82998-12160
12volt Relay
Step 1
Determine if your HDJ81 or FJ80 has the factory locker wiring harness. Takes about 5 minutes and from what I've read most of the unlocked trucks come with the harness already in place. Just remove the passenger side kick panel and look for the ECU plug. On unlocked trucks it is tucked into the body panel
If you have the ECU plug, then you will also find the plug for the OEM switch in the dash
