Ignition switch
Is there a way you can bypass the clutch safety switch and rig the ignition so it is off of a push button instead of the key? Not that it's a big deal, but it's a pain to lean down and push the clutch in and the turn the key at the same time.
I have this rigged up on another pickup because the ignition rod that connects to the lock tumble has worn out too many times. I'm not sure if I can do it the same way, or if there's a better way to do it.

You can get the clutch bypass harness off an auto truck at a junkyard. The wiring harness is the same for both trucks, and the auto gets a bypass at the clutch and the manual gets a bypass at the transmission.
Look under the dash where the clutch would be if it was there.

i cannot tell you what 2 wires it is for our trucks. but you just have to put them together.
On my 95 I made pieces to clip into them so i didn't have to destroy the connectors. Then i ran a switch on the dash. That way you had to know to flip switch to start the truck. hehe. =)

Actually ke5chn, That is incorrect.
There are multipul switches under there.
Thats why you have to grab the right wires for it.
2 are just for starting, 2 are for cruise control, and tehre is still another 4 under there if i remember. there is 6 or 8 total wires for the clutch.
I am pretty sure it was the 2 purple ones.
I just poped the connector off and pulled the pins. YOu can probably just tape them together.
The truck knows no different if those are together, cause all it deals with is the starter.
So accidental turns of the key result in grinding some starter teeth.
I did that once or twice.

That switch is, electrically, two separate SPST switches. When the connector is in place, the two wires closer to the front of the truck are for the starter circuit, and the two toward the rear of the truck are for the cruise control. When you first start to move the clutch pedal, the cruise contacts open, and when the pedal goes all the way to the floor, the starter contacts close. So yeah, jumper the two terminals toward the front of the truck. Just remember what can happen when you do that....

I used to do that in my f150. Just turn the key in first gear if I was on a slight downhill.
The problem is the truck doesnt know what to do, so you still gotta push in the clutch otherwise it just ca klunks back and forth like you have no idea how to drive a stick.
I woudlnt' do it in a diesel though.

I've actually intentionally bypassed this switch in the gasser cars I drive. It's come in handy a coupla times; once with a broken timing belt (non-interference engine) and once with a slush-sodden distributor cap. Turn the key, let up the clutch, and let the starter "push" the car to a safe spot. Emergency use only, of course! I figured the starter wouldn't produce enough torque to push one of these trucks, and even if it did, given the size, I don't think I'd _want_ it to.
But it's also good to know how this switch behaves when you have clutch trouble. If the infamous pivot bushing craps out, the pedal doesn't push the pushrod and the engine doesn't start. If the equally infamous hydraulics crap out, the pedal DOES push the pushrod, so the starter will engage, but if you're in gear, it'll either lurch or bog down the starter.

If you get the upgraded starter. You can probably haul a trailer with the starter. haha!
I wish I could afford this.
the guy who got the truck this went on sold the engine and just took the cab, scrapped the rest of the truck. Really crappy deal
