ATTN: Transalper - locker questions

[BajaTaco]

I was going over the locker page on your website, and I wanted to ask you a about a few things.

1. You said... "When I ordered the ARB switch, they sent me a compressor wiring diagram which included directions about how to use a non-ARB compressor - ARB customer service impressed me once again! "I would think this is pretty obvious, but if there is anything I should know - Do you still have these directions? Is there any way I could get a copy from you? I found a picture of a wiring diagram (http://home.earthlink.net/~larsdennert/4runner/arb/arbwiring.JPG) on Lars Dennert's site, but it is blurry.

2. You said... "Install a hidden shut-off switch so the front locker cannot be accidentally engaged. Engaging the IFS Locker in 2wd will cause the front drive shaft to go from zero to your current speed instantaneously and potentially cause severe damage." Can you elaborate on how you did this?

3. Where did you get your e-locker switch? (Toyota factory switch) I assume it was part of your ECU harness stuff that you bought at a scrap yard? I thought it would be cool to use a Toyota factory locker switch to operate the ARB. I thought I saw a picture somewhere a long time ago where someone used one, and actually changed the writing to read "FR Diff Lock".

1. I can make a copy of the wiring diagram and send it to you. Or you can just call ARB USA and they will send it. It's pretty straight forward. The compressor switch does two main things: (1) activates a relay that turns on the compressor and (2) sends power to the locker switch.

2. I just installed a SPST switch in the positive wire that goes to the compressor switch. I have it hidden behind the dash.

3. My e-locker switch was another junk yard find. It should be pretty easy to use for the locker. The positive to the locker switch would just need to be controlled by the compressor activation (so the locker only turns on when the compressor is activated). The locker switch then activates the solenoid. Personally I like the two ARB switches since they fit so well in those two spots on the dash.

Have fun!

I get to do a little electrical trouble-shooting this week as well. My e-locker dash light stopped working for some reason. The e-locker is working fine, but I seem to have a bad ground somewhere between the cab and the rear diff. Luckily it will be getting into the upper 30s this week so I can work outside!!

OK, I can call ARB and get it from them. When you say compressor switch - do you mean a switch that you control from inside the cab? I am assuming this is what you mean. I currently have a switch located in the back of the truck, near my compressor, that turns it on or off.

2. I just installed a SPST switch in the positive wire that goes to the compressor switch. I have it hidden behind the dash.

I see. I thought maybe you had something tied into the 4wd actuator wiring so that the locker switch only had power when the 4wd is engaged. Maybe I should try that so it will be automatic.

Yea, Ilike the two ARB switches also, but since I already have the facotry locker switch, I thought it would be cool to match it. I am still thinking about the wiring for the compressor though. Couldn't I just connect the locker switch to the solenoid, so that when I push the button, the solenoid is activated, and draws air from an air tank, which is regulated by a pressure switch connected to the compressor? That way, I don't need to turn the compressor on manually. The pressure switch will sense the when the air pressure drops and turn it on automatically.

Good luck. I know what you mean, I was doinga lot of the work on my new camper just before the Mexico trip in below-freezing weather (I don't have a garage). Oh well. It keeps you tough http://www.4wdtrips.net/forum/emoticons/wink.gif

Yes, I mean a switch in the cab.ARB has it set up so the compressor switch acts as an isolator for the locker switch.

2. I just installed a SPST switch in the positive wire that goes to the compressor switch. I have it hidden behind the dash.

I see. I thought maybe you had something tied into the 4wd actuator wiring so that the locker switch only had power when the 4wd is engaged. Maybe I should try that so it will be automatic.
I do not have anything automatic in place yet. When you figure it out, let me know. :)

When I have a little free time I want to figure out how to automatically disengage the ABS when the locker is engaged. I think it is a simple one-wire to ground mod . . . We'll see.

3. My e-locker switch was another junk yard find. It should be pretty easy to use for the locker. The positive to the locker switch would just need to be controlled by the compressor activation (so the locker only turns on when the compressor is activated).

You can do that if you have the compressor on all the time (or at least when you are off road). The advantage of having two in-cab switches is that there is less likelyhood of accidental engagement.

Do you have any spare spots for switches in the center console? A pair of black OEM (FR Diff and RR Diff) locker switches would look really slick in that location.

No, I don't have a console - I have the 60/40 split bench seat. Someday I would like to get buckets with a console though. I came within a couple bucks of winning a pair of late model Volvo power/heated seats on Ebay last year - that would have been sweet http://www.4wdtrips.net/forum/emoticons/biggrin.gif

My center dash area is pretty well devoid of any useable real estate now - too many gadgets http://www.4wdtrips.net/forum/emoticons/rolleyes.gif

I am working on a schematic for my ARB that I will post when I get it finished (figured out). I could do a really simple setup just to get it operable, but of course I am scheming of ways to make it complicated http://www.4wdtrips.net/forum/emoticons/devil.gif

Jay, do you by any chance have a pic of the locker switch, so you can tell me which side is the "top" and which is "bottom" http://www.4wdtrips.net/forum/emoticons/lol.gif Like a dumba$$, I took the label off of the front of the switch without marking the switch body. So now I don't have the proper order of the elec. pins that you shared with me http://www.4wdtrips.net/forum/emoticons/rolleyes.gif

If not, I can probably just look at the rear diff lock switch when I get the dash torn apart.

Thanks

Been there . . .

Near the connector there is a code written on the left side of the switch - 931-1R73 (or something like that) - the 9 is the top of the switch (where the un-used pin is located). Also for reference, the gray circle thingy is on the right side of the switch as you face the button.

Hope that helps.

Jay, U DA MAN!! I'm not sure if you enjoy beer, but if we ever get together, I owe you a couple...

OK, now it's time for me to finish the cosmetic surgery on this locker switch...
