I'm installing an Adaptronic on my SA 1st gen, and there's no clutch switch. I was wondering if there's one I can retrofit or if I'm going to have to find one off of a GSL-SE or 2nd gen.

I really want my idle control to be perfect, and after watching Andy's videos, that's the strategy he recommends. I know I have a neutral switch off of my transmission, so that should be OK.

 

81-83 GSLs with cruise control will also have a clutch switch, as will 84-85 non-GSL-SEs with cruise control

 

I'll go one better for you.

Genuine part number for series 2 is B001-66-940A. Superseded by B001-66-940B. Fortunately this is the same as multiple Mazda models including B series and Miata and you can get aftermarket replacements everywhere. Google or eBay this part number. Genuine Mazda still available too and is $20, eg RX7 Miata MX6 Protege Brake Light Stop Switch 81 82 83 84 85 89 90 91 92 93 | eBay

 

Awesome, thanks so much.
