I'm getting close to finishing up on my auto trans to manual 5-speed install. The SST manual states that this is a normally open switch that will complete circuit when trans is in neutral. One question, can this switch and wires withstand the loads of being in between the ignition switch and the S terminal on the starter? I really don't think the wires can. Plan A, I could use the switch that came with the trans and remove the plastic cover and wires and use 14 gage wire. Plan B, I could install a switch on the clutch pedal. Not sure if anyone sells a switch that I could just attach to the pedal assy. Any advice would be appreciated. Tim

I like plan B better, all wiring stays inside the car and you wont have to put the car in neutral to restart in case of a stall.

If you want to use the switch but are concerned with the load capacity you could use a relay.

Looks like you gave up on the Richmond Gear transmission, what happened?
Thanks

I tried to by one from Ecklers, after over a month they cancelled my order said it was discontinued. Then ordered from Summit, After a couple weeks, they also cancelled. Ordered again from Jegs, They kept on changing delivery date so I cancelled the order. I don't know how Richmond can stay in business. I did call Richmond Gear and they told me they were waiting for a part to start the trans that I ordered. So I went with a TKO500 from SST.

I would do whatever it takes to bypass that neutral switch and put one on the clutch. Lots of reasons, they will be obvious if you think about it.

I think your right about placing the switch on the clutch, that makes a lot of sense. Last night I spent a lot of time searching the internet for a switch, no luck. Somebody on this sight must have the answer. Anyway, Monday I will call SST and find out what their neutral safety switch is rated at. There might be other switches out there that could plug into the trans and work just fine. Tim

Here's the '69 Camaro clutch safety switch (first year it was used); it interrupts the purple "start" circuit.

Thanks JohnZ, Thats looks real similar to the 69 vette switch. Your pic is the first one I've seen installed on pedal assembly. Tim

I have a TKO 500 (Keisler version) in my '67. I did not use the NSS and do not see the need for one. It's not that tough to remember to put it in neutral/push down the clutch when I start it - and it's a LOT simpler than wiring it all up thru the ignition.

As far as I'm concerned it's just another "nanny" that isn't needed and can go bad/get out of adjustment and cause more problems than it solves.

I mounted a hood pin switch (the kind used with alarms and remote start systems) to the clutch pedal using a simple L-bracket. The switch opens the circuit when pressed against the firewall. You can use a brake light switch, too, or any other similar switch but I like the durability of the hood pin switch. You can get one on eBay for $2. If you have stock wiring, I'd run the solenoid power from the starter switch through a relay and trigger it with the pin switch, such that the car won't start without the clutch being depressed (as in any other modern car). It's very easy to do. Mine works flawlessly.

Shouldn't that CLOSE the circuit when pressed?

Mike (Naples)

The pin switch works opposite to a brake light switch, that is, the default position (when the pin in extended) is closed (i.e., grounded) and the circuit is opened when the pin is depressed. You use the middle contact on a standard 5-pin relay and need to run a good ground to the pin switch.

65GGvert

I don't understand the grounding part. The switch is in line with the 12v starter voltage to the solenoid, you wouldn't short that to ground. You would interrupt that voltage when the switch is open, and then when you push the clutch down to close the switch to allow the voltage to the starter when you turn the key. The switch should be open anytime the clutch isn't all the way down.

OK, I just spoke to one of the tech support guy at Tremec. He said, If I use the switch that came with the SST transmission kit that would also need to install a relay. I like the switch in JohnZ's post or no switch at all. Just one more thing to fail down the road. After all, the 1966 corvettes with manual transmissions didn't have them. Tim
