Hey Bob,

I am not running a front locker, but it is sometimes nice to be able to back up a trailer in 2wd low gearing. With an open front diff and this mod you could easily do that. It's sometimes a little trickey backing up the trailer into the carport when the sunlight is on your back windows and I am going around a corner into a dark carport. Slow is nice then, don't have to play with the clutch.
Looks like I was right (thanks a bunch double down for the diagram) on the relay switching between the two solenoids.

I attached a real crappy pic of the changes

 

Ahhh... thats a good idea!!! have you seen this??

at the bottom... the twin sticks.... SWEEEEEET

 

By " I was right " you mean the relay is under the dash??? if so where did you locate it??

 

I've seen the twin stick, but this will do the same for me and it looks better imo. We were also talking about the poor people up here .

One of the diagrams shows the relay in the neighbourhood of the ECU, I am guessing behind the pass. side kickpanel or behind the glovebox.
I tried moving the 4wd lever with the ignition turned on (engine & radio off) and I could hear the relay click in that area. Should be easy to find once I take the glovebox and the kickpanel off. I have the mechanical old school 4wd lever, but it should be the same with the 4wd button.

I also noticed a wire going to the abs unit from the 4wd switch. I bet if you take that and ground it you'll disable the abs system. I haven't seen those diagrams before, everything looks quite simple.

 

Thats good to know... if the relay is right there this mod could take no time at all... hehehe I love it....

 

We will call it MDD manual differential disconnect!!!!

 

This is a very good idea. Can't wait to see what comes of this.

 

aka "the MDD mod™" from here on

Once I get some more time I'll do it also. I still have yota button laying around somewhere which would be good for that.

 

Well I may spend some time this weekend and play around with this... My rear locker is not working right now either, so this may be my chance to spend some time and get both working

 

Subscribing, sounds like someone like me, a working student, can do on a budget.

 

get your ride sorted bob! at least your rear locker... n lets go wheelin! ive got TWO get out of jail free cards from the mrs for april 8th and 15th (easter weekend). if i dont go at least 1 of those days, ima cry like a lil

arjan, oscar, sizzlechest..any other lowermainlanders interested? maybe ill start a new thread in the off road trip forum, or the ghost town forum aka bc community haha...

 

Sonny, the 8th I may be helping my buddy put camaro FI in his throttly body injection K5 Blazer, but if that falls apart then I may be interested for that weekend... and easter will get me killed!!!!

I think the runner is going to need a rear Elocker actuator, which is $$$$$... I am going to run by NSOR on friday and ask about a cable locker kit for it... I am also going to look into rock sliders too....

 

yeah...getting killed easter weekend will kinda suck. ive got the inlaws intown that weekend, so if i dont end up wheelin, i can finish up all the bolt on mods ive been putting off (isr, deckplate, breather). ill put up a new thread in off trip planning...hopefully all 3 of the bc'ers see it..haha...

edit: you know you want to

 

Did anyone complete the MDD mod?

I am looking for a simple way to unloack the front so I can back up my trailer in low range.

 

I haven't gotten around to it yet, my rear locker also quit working in the meanwhile, more stuff on the list.
I will work, maybe in spring I'll take a look at it.
