Push Button Start (daily driver)
I found this on another forum about VWs.
quote: 2.0 Push-Button Start howto: (might be same on vr6)
This worked on my 96 2.0, so now Ill tell everyone else how to do it properly after i made the mistakes
You still need a key to start the car. you put the key in the ignition, and turn it to the on position, then you can hit the start button.
1. Find yourself a hefty starter button (should have 2 electrical terminals and be able to handle a decent amount of power.) available at most speed
shops.
2. get some 10 GA wire, cut 2 pieces off approximately the length of the distance from the ignition switch to where you want to mount the button.
3. Disconnect the negative battery terminal
4. Take the 2 screws out of the bottom of the plastic shroud around the steering column
5.Disconnect the connector on the passenger side of the steering column, it should have like 6 wires in it, 2 big red ones, a black, i think a brown..
you'll know which one it is, it plugs directly into the ignition switch.
6. Splice one of the 2 lengths of wire that you cut into the fat solid red wire. Solder them together to ensure a good connection. This will be your
"hot" wire. Be sure not to cut this off the conector as it supplies the rest of the stuff on the switch with constant power.
7. Here's where you get to make a decision. There is a fat red wire with a black line on it. this is the wire that delivers electricity to your
starter selenoid. You can either clip this off the connector, or you can splice into it. Chose whichever you are more comfortable with. (clipping the
wire off the connector means that when you put the key in, and turn it all the way to the start position, nothing will happen.) If you clip it off the
connector, splice into the side of the wire that goes into the cars wiring harness, not the connector. Solder this splice to ensure a good
connection.
8. Use shrink-wrap or electrical tape to be sure the bare wire from the connections you just made wont touch anything on accident.
9. Connect each wire at the other end to one of the 2 terminals on the starter switch.
10. Mount your starter button wherever you decided.
11. you're done, this should have also over-ridden the clutch safety switch, so watch out.
I did this mod out of necessity, not for glory or fun. my ignition switch was going screwey and wouldnt allow my car to start very easily, so rather
than pay $160 for a new assembly and dealership labor ( i guess they have to install it for some reason) I paid like less than $20 in parts and did it
myself.
I have one, VW that is, and would like to have a start button. The switch I have is rated to one amp so I thought about using a relay, although I do
have a few questions:
1) Will the switch be able to handle the voltage/current from the relay?
2) Will a 40 amp relay be suitable for the job?
3) What rating should the wire be that connects the ignition to the relay?
4) What rating should the wire be that connects the switch to the relay?
3) Would anyone else do it a different or better way?
Any help much appreciated

Wire the switch from the battery pos terminal and the second connection to the starter solonoid?, sometimes it's handy to be able to crank the
engine without starting it {ignition off}

Think in the interests of retaining the vehicle for a significant amount of time I'd rather there was a key involved somewhere.

Surely someones handy with electrics. There's a big thank you in it for you if you are.

We did something similar on an old Iveco because the switch was dicky. We used a wire from position 2 through the button to replace the cranking feed
but it was just a case of splitting into the appropriate wire as it was already wired through a relay. We were changing where it got its power from so
in position 2 just press the button.

yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

You just need to identify the connections on the back of the ign switch.
1, +12v from battery
2, +12v in acc position
3, +12v in acc+run position
4, +12v in run+start position
connect your button across terminals 3 and 4 as described above, that way you can still use your key start if you button fails
don't laugh at the pic........

Your better off using a relay to take the starter load and using a start/stop button meant for control. This way there are far more start/stop or just
start switches available that look a whole lot better and better suit a dash.

thats irrelevant anyway, cos the solenoid deals with that. A big switch or a 30A relay is more than adequate to switch the solenoid. You could work
out from the size of the wires to the ign barrel what the max current draw is, and pick a switch to match. As an additional precaution, you could also
add an inline fuse to prevent damage to the wires and switch.
on a sierra, this would be so easy as to be a joke. The main problem you face is identifing the wires correctly, and not screwing up any other
circuits.
I would just work out which wire goes to the solenoid. Then take a live from the battery, to a hefty switch, using wires of a similar thickness to the
ones on the ignition barrel. Pick a switch with a similar rating. The send a wire from this to the ignition barrel, and splice it into the starter
wire. Simple as pie!
