Manual Switch Bypass Glow Timer
BJ60 Bypass
To not get credit where credit is not due, kudos to master Toyota Tech Ciaran Wilson of BC. He has run this system in his BJ60’s (or variations of) for at least 5 years.
I do not take detailed notes, such as pin # on connections, so if anyone who uses this wants to add to the tech sheet feel free.
The fuse panel has one 7.5amp fuse marked Glow. In reality, all this fuse does it light up the glow light on the dash.
Access the glow timer in the kick panel on the drivers side. Undo the factory connection to the glow timer. Among all the wires heading up the harness are two black/red wires (opposite ends of the plug). One goes to the high end glow relay, and the other goes to the afterglow relay (picture supplied on this post; I removed the cover of the relay so it would identify easier---the one you want is on top of the inner fender, not the one beside the starter relay). I pushed a wire into one connection at the kick panel, and ran it out the door and to engine bay. I simply completed the loop at the battery using the age old “push the bare wire onto the positive pole” method, and listened for which glow relay it activated. When I got the right relay I marked and cut the wire at the harness in the kick panel.
I took the instrument cluster out, and cut the two wires going to the glow light, in effect severing the light from the harness; I believe one is black/red and one is red/white. One is powered when the key is on ACC (I think it was black/red). This is the one you want to run to one side of the NO switch. Dead head the other wire.
Run two wires off the other side of the NO switch: One to the glow light bulb pigtail you left yourself, and one to the black/red wire that heads to the main relay from the drivers side kick panel area.
Run another other wire from the back of the glow light bulb to ground of your choice (I took it to a bolt on the firewall).
Test the system, then finalize all your connections. With the key is out, you should be able to press the button, and nothing happens. Turn the key to acc and when the button is pressed current should go through to both the glow light, and the main glow relay, tripping the relay and glowing your plugs, as well as turning on the glow light.
Make sure your connections are sound, shrink wrapped and put back together; enjoy.
This system has been used for at least 5 years with no issues appearing. It works great on my truck. Wire it in at your own risk.
Leave the glow timer right out of the system, and you have a totally manual system. You could hook the timer back up, deadhead the one black/red cut wiring coming out the timer, and in effect have total control of the high end glow and still maintain the afterglow, if it still works.
I have not yet changed out the plugs from the 12V super glow Toyota=19850-68050 (51) 12V-6V to the manual glow 12V Toyota=19850-68010 12V-10.5V…one day.
Brownbear, I suppose one could not sever the connection at the timer relay, and simply T into that with the above wiring system. You could then “super afterglow” the system with the button if you choose.
Alternatively, you could check the wiring and see if you can do much the same as the 13BT/12HT glow system fix that Mike Forbes pioneered. I believe Stone has some excellent posts further defining this override on Mud. I have not confirmed, however if it is the same you can tap into the water sensor loop for the glow with a normally closed switch. When you push the button you in effect mimic very cold weather, and fool the system into glowing as long as the button is pushed. When you release the button, the normal glow cycle happens. Again, I have not checked to see if this would work with the BJ60 super glow system; I figured plan old manual would be the best for me.
