Ok, the little rod thing inside the ignition broke and I'm not tearing apart the steering wheel. I have a 30 amp push button. Where is the best place to connect this to install a push button starter... you know turn the key to "On" and push the button? Across the "S" lead and the silver post on the starter relay?

Wouldn't activating the starter relay small wire on the rt fender do it, it does when you turn the key.

Yes you need to wire to the fender mounted starter solenoid, just send positive to the small terminal.
You could wire direct to the starter mounted solenoid, but I see no benefit to it and you'd be running a lot more amps through the switch.

Remove the nuts on the "ignition switch" on top of the column under the dash. Leave the wires connected. Hook a circuit tester up, and with key in "ON" position, slide the switch mechanism until you find the wire that makes engine start. Splice the new "momentary switch" into the start wire and to ground. This is the way I have mine done. /ubbthreads/images/graemlins/smokin.gifOkieGringo

1st Make sure the back of the button isnt hitting any metal dash supports/ causes arc and fire. 2nd Make sure your button cant stick on, starter doesnt like that when the engines already running. I hope you can learn from my mistakes!

I did the same thing on my '80 when I didn't feel like pulling the steering column apart. I ran a "hot" wire (with fuse) to an industrial push button switch to the starter solenoid. Been good for the last 10 years plus.

Why does the key have to be on? Does part of the circuit or ground travel through the key cylinder as an antitheft mechanism?
Since I pulled the whole box out, I'm going to hook up two buttons, an ACC on and a START. I have all the connections for each mapped out, although I did notice that during the start cycle it disconnects some accessories and applies power to two others -- why the two others, what do they do?
Also, I will have no easy way of disconnecting the one that normally gets disconnected during the start, I assume this is ok to ignore since it just eases the starting load?
What two pins connect that make it start? During my testing it was 2+1, but it doesn't seem to run the starter for me.

You would need the key in "ON" position to unlock the steering wheel in your case, but since the mechanism that pushes the rod down is broken, it's not necessary. The wire that I spliced into runs to the starter relay on the pax fender wall. I have no clue what the other wires go to. Maybe one to the starter relay and the other to activate the IP connections /ubbthreads/images/graemlins/shrug.gif. OkieGringo

Ok, got that taken care of. I tapped the starter lead that was in the box itself instead of going to the fender.
Now I have one last question. When you turn it to start, the left center pin and the upper left pin in that "Box" connects. Pin a and 1 in my diagram that did not format correctly above.
You then apply +12v to this connection to start the engine. What harm will be done if I leave the circuit connected between 1 & 2 and just remove the +12v once the engine has started (turn off starter button)?

And darnit, why do these toggle switches from wal mart have a +12v, LOAD, and Ground? Can I ignore the ground? I only want to complete a circuit to an existing wire, not complete it to ground.

You only need 12v and Load. The ground is only if you want the switch to light up when "ON."

i did that a year ago used a spring loaded toggle switch so it always returns to off. you still have to have a key that works so you get power to the fuel shutoff sol. & glow plugs. I just turn my key to rin wait on GP's then toggle down to start.

Mine has a pushbutton that auto springs back out when no pressure is applied, helps the starter. I am not sure what combination of wiring I used to do my button, but I know the truck will crank endlessly with out the key on but when i turn the key and press it, it will start right up. I dont know why but I guess its good anti theft, but that just so happened. I didnt plan it that way.

If you don't have power to the FSS it won't start. The vehicle needs fuel to run. If you put 12v to the FSS and hit the starter button it will run.

It's alive!
Well, I ripped out the box and found the wire to the starter and then realized that it was going to be virtually impossible to hook the broken sliding rod junk back up without pulling the column. I simply couldn't see what the hell I was doing above the steering column.
So it was quicker just to map out all the tires and hook up an "ACC ON" switch on the dash too. Now I turn on the accessories (which hits the glow plugs) and hit the starter button to turn her over. When I turn ACC off, it shuts off... just like the key. I through the lock cylinder in the trash.
I used the broken "mate" off the slider assembly to do my wiring. Hell, someone should make a switch and button pre-engineered to plug and play into the harness... although that would make a theifs life way too easy.
I didn't enegize one circuit when I can't figure out what it does. I can only assume it's the diesel fuel pre-warmer? Who knows... But it works.
Thanks guys!

I use the fact that my truck is rusty and 21 years old as my anti theft!

How big of a fuse would you want on the switch's circuit?
Someone mentioned a 30 amp switch. I was just gonna use a toggle switch and an inline fuse....
So you don't need a huge fuse because you're sending power to a relay, right? Or else you'd need a giant fuse?
Is 30 amps enough just to be safe?
So forgive me for asking this, but you connect one hot on the switch to 12v, the other to the little terminal on the starter relay on the pass fender that the ignition switch plug comes off of, and the ground to a ground?
What gauge of wire would i want to use?
Is the only reason why you can even do this because you are hooking the switch up to a relay? i asked a guy about this and he said you would burn up your wires.. maybe he wasn't thinking of running it through the starter relay and he thought you would be sending all that juice through that little wire and switch when you start up..
THanks
