Another neutral safety switch question

I realized last night that my 6-speed (T56) does not have an integral neutral safety switch like I thought... I guess I must've confused the 5-speed (TKO) with the 6-speed. Looking at what I've got to work with and taking into account that I have a very strong desire not to disassemble the pedal assembly I finally decided that the easiest solution would be to fab a bracket to hold a switch at the clutch clutch pedal. It looks pretty straight forward except for some fairly tight access issues (I'll have to stretch my muscles before attempting this). I plan on using the same type of switch that I used on the brake pedal for this function. My question is this: Can this switch be simply hooked up in series (and handle the current) or does this switch need to feed a relay? I've looked through quite a few posts on this and other site and I'm pretty sure that it will handle it but I just wanted to make sure before I button everything up.

Re: Another neutral safety switch question

A brake light switch is not set up to handle the current from the ignition switch; just look at the difference between the wire gage of the purple and purple/white ignition wires (12 gage in and out) and the orange (14 gage) and white (20 gage) brake light wires.

I'm a little confused about the "wire in series" part of the question too. The clutch safety switch will just go in line in place of the factory neutral safety switch; it should have the 12 gage purple/white coming in from the ignition switch and the 12 gage purple from the starter coming out. It is not in series with any other switches.

A relay is needed on a TKO if you use the TKO's NSS; for what you're doing, no relay is needed if you use the right clutch switch.

You need to use either a clutch safety switch from a later car (I have no idea how they are mounted and triggered), or just use a 69 setup. If you search "clutch safety switch" here you should find pics of my OE setup, and there are threads about other guys backfitting the 69 setup to their cars.

Re: Another neutral safety switch question

Thanks for the input. I guess I'll will look for a clutch safety switch to use instead of using a brake light switch (I thought that they may actually be the same switch). I'll have to look into the physical size of the clutch switch because I am extremely tight on space in that area. If I can't fit it in the space then I'll go ahead and use a brake switch and drive a relay with it (since I can mount the relay anywhere under the dash).
As far as the "wire in series" part of the question, "series" is an electrical term to denote "in-line" wiring of a switch as opposed to "wiring in parallel" which denotes wiring along side of something (switch, resistor, etc).... that's about all I remember from my DC circuits class.
